Sealing a Motorcycle Gas Tank with the KBS Cycle Tank Sealer Kit 

Dead Eyes love it. I’m doing this on an ‘81 KZ250 and am gonna employ your method but for the filler side since the cap is a little funky. Thanks

Thanks Corey. I notice the same thing on these videos...none of these guys ever use a sport bike tank for demonstrations..they use the older traditional tanks, because they are much much easier.

Just use an automotive magnet on an extendable rod to get the nuts, bolts, steel, BBs out.

Awesome tip. Thank you for sharing!

Excellent! Thanks for your feedback!

Thank you I used your comment and mine turned out great. We must have the same tank mine was leaky in some places that shop vac was the reigning champ.

Great! If you have any questions at all, please contact is before you start your tank. www.kbs-coatings.com/contact-us.html

Hey mate.... hope you don't mind me asking.... but doing my dl650 vstrom tank.... the fuel pump hole is ENORMOUS any tips on how to seal it off?

@@acagz536 How did you go with that? I'm about to do my VF750F and it also has a large hole foe the fuel huage sender unit. As the sender itself is pretty rusty I'm thinking of taking it off the base plate and using the bolting the plate back on and get a new sender.

And make sure you wrap the cork or plug with plastic

Can I use the same (duct tape/electrical tape) with the paint stripper? Or do I need to use a rubber gasket where the petcock valve goes? I have a Suzuki Bandit 600, and it has several opening that will need to be covered in order to use the stripper.

41 seconds in. It was shiny clean to begin with.

Agreed

Did you get an answer to this, I'm worried about the same thing

I believe that’s the Zinc Phosphate he explains, you get in the video. Read some comments as well; some replies explains that this is normal and that it is what the Sealer Adheres to. If there are any doubts wash it all out, use Acetone then check out Red Kote tank liner; similar process. However this product has way more instructions and a complete kit, versus buying everything individually; seems to have very promising results. Hope this helps ✌️

Mine came with a rubber plug. Had no idea what or was for until this video. LOL!

No flash rust is 100% normal. You can always reuse the strained and captured RustBlast. And a nice rinse with water is all that is needed. And like you did, dry the tank well after rinsing. RustBlast will leave behind a dusting of zinc phosphate that aids in the adhesion of Tank Sealer.

Yes. Tank Sealer is impervious to water and antifreeze. This is a very common application.

Yes, most would remove the EFI and then screw the plate back on. You can protect all screws and threads with petroleum jelly as the Tank Sealer will not adhere to a greased surface. Some people also tape heavy plastic over the hole (like painter's plastic), but the tape can leak at times depending on the strength of the adhesive of the tape. Does that help?

Neta Family good looking out.

Neta family how the hell didnt ya know too much heat would do that

@@itsapodcastrophe Not everyone has experience in such matters, and everyone has to start somewhere.

MEK is the best to use but don't get it on your paint... You need to fill the tank to the top and wait 24-72 hours for it to break down the coating. Also where gloves and a proper mask to avoid inhaling the fumes as it is Toxic!

Yes, a small amount of flash rust is normal and will not affect in any way the adhesion of the Tank Sealer.

Hello, did it work. How is the tank sealer holding now

@@nithinkvijayan2708 it's holding up fine. No issues. Worthy of investment

Use KBS Strip: www.kbs-coatings.com/KBS-Strip.html

Use KBS Strip for the most effective removal of an old failed coating. Pour some KBS Strip into tank and carefully rotate tank to allow contact with all sides. It may take multiple applications of KBS Strip to finish the job completely. Old Sealer may come loose in big chunks or small pieces so use a long tweezers-type tool to help remove it from the tank. After stripping is complete, rinse tank generously with water and proceed with the KBS 3-Step System for Fuel Tank Preparation & Sealing. (NOTE: When stripping a Fiberglass Tank, surface contact with the stripping agent should be kept to a minimum to avoid the attack & weakening of the fiberglass resin.)

Yes, prep and seal the tank first and then do the filler work.

Yes, it is always best to remove the old sealer first.

+Oggy Bleacher I put a bolt wrapped in electrical tape snug in the hole. and pulled it while draining the tank through the top fill hole with the coating draing away from the petcock hole. 1974 Honda CB360

It is best to apply some grease to the threads. Tank Sealer will not stick to the threads.

Yes, the KBS 3 Step Tank Sealing System can be used on old rusty tanks and new tanks.

was thinking the same thing .. nice save from KBS here ey .. oh oh it can also be used on a new tank .. wanting everyone to think its an old rusted out tank .. but instead its a new one painted brown to look "old" then scratched up a bit

+Nathan Garza As long as your powder coater keeps temperatures at 400F, the Tank Sealer will be fine. To be on the safe side, we recommend the power coating first and then the Tank Sealer.

Do you have surface rust or flaky rust?

It is best to do the powder coating first. That said, as long as your powder coater keeps the temperature at 400F, that will not harm the Tank Sealer after it has fully cured.

You will utilize pipe cleaners to keep the petcock open. Pull the pipe cleaners after the Tank Sealer has stopped moving and BEFORE the Tank Sealer cures.

+Trevor Headtrip "while simultaneously sealing small pinholes and weld seams".

We usually use a chain so once you can fish a small segment of the chain out, the rest of the chain will come with it.

Yes, if you did not keep the fuel line open during the sealing process (with air), then after the Tank Sealer has fully cure, you can drill through it.

@@Kbscoatings-us Hi, Is this product have an oder, Would like to do my tank over the winter in my basement or out in the garage, Can it be used in cool weather 30* or 40*. thanks. George. Niagara Falls, n.y.

@@nicolec.6303 Application temperature is 55-82F. Please keep it in that range. If you use it indoors, please be sure you have plenty of fresh air.

Yes, you can use the 3-Step Tank Sealing System on a carbon fiber tank. The procedure for sealing a Fiberglass Tank is the same except for a variance in Step #2 - RustBlast. For this type of tank, thoroughly wet the fiberglass surface for only 2 minutes using RustBlast. Drain and rinse well with water as directed. Because you are not prepping metal or dissolving rust, RustBlast may be saved and re-used for future use. RustBlast will, however, treat the fiberglass surface by giving it a more acidic pH level & by leaving a zinc phosphate coating ideal for Sealer adhesion. Also, it is important to make sure that the tank is completely dry inside before sealing. Drying is best accomplished by introducing forced air into the tank by using a shop vac, blow dryer, or fan. (NOTE: Drying is a critical step for sealing fiberglass tanks. Fiberglass tends to hold moisture and if the tank is not dried completely, the Sealer will not adhere properly.) IMPORTANT: It is also very critical to methodically coat the entire fiberglass tank completely & thoroughly with the Sealer. If any part of the fiberglass surface should accidentally be left exposed or unsealed, however, these unprotected areas will be very susceptible to deterioration by alcohol blended fuels and it is therefore highly recommended that these fuels not be used in fiberglass tanks even after sealing. After coating the tank, remember to drain well to avoid pooling and puddles.

Until the Tank Sealer is set up enough that it is no longer moving on the inside of the tank.

@@Kbscoatings-us Thanks. With a baffled 4+ gal tank and 8 oz sealer, an hour after pouring in there was no way to hear or see the sealer moving. Was asking for the next guy.

After a thorough coating inside of tank, patiently DRAIN ALL EXCESS SEALER from tank until it no longer drips sealer. Additionally, to avoid puddling and pooling of excess sealer inside the tank, rotate the tank side to side every 5 minutes. This step is especially IMPORTANT if design of the tank makes complete draining difficult. This additional rotating of the tank will help minimize excess accumulation in any single area, and result in a slightly thicker coating on ALL walls inside the tank. Foaming and bubbling are signs of excessive Sealer accumulation and gas entrapment due to ineffective drainage.

The KBS 3-Step Tank Sealer System is absolutely ideal for new tanks. If you leave a new tank uncoated, it will eventually rust leaving you with clogged fuel filters. A very common misconception with sealing new tanks is that you do not need the KBS Klean and RustBlast. New tanks made of new steel are very slick and not an ideal surface for Tank Sealer to stick, so we always recommend KBS Klean and RustBlast to properly clean and etch the surface of the new tank so the Tank Sealer can bite into the surface and adhere permanently.

Typically, it burns off the Tank Sealer in the weld spots. Can you do the welding before you do the Tank Sealing?

@@Kbscoatings-us thanks for the response. I have a very narrow crescent moon shaped crack on the under side of my tank. It's where one of the bolts holds the tank to the frame on my old Triumph. 55 years of past owners over tightening that bolt and it finally wore through the metal and created a leak. I'm not sure if lining the tank will fix it, so I'm worried I'll do the lining then end up at the welders if it doesn't fix the leak. That's why I was asking what would happen to the seal if I had to weld part of the tank. If welding one spot would burn off the sealer, would you just seal it again?

@@daveco1270 Yes. Clean up the weld mess on the inside of the tank with KBS Klean. Then apply a dust coat of Fusion SEP. Rolling the tank around and drain out the excess. Then do the Tank Sealer Step again. Tank Sealer does not stick well to itself so that is why you would use Fusion SEP.

KBS Strip will remove an old sealant: www.kbs-coatings.com/KBS-Strip.html

Carefully Pour entire contents of can into tank and slowly rotate and roll tank until all sides are evenly coated. Patiently work with it for a minimum of 20 minutes but no longer than 1 hour, periodically checking inside.If an area needs extra attention, prop the tank so that the excess collects on that area. Continue this until the majority of the remaining sealer is loosened and/or removed.After Strip has been allowed to work, pour out & capture into an appropriate metal container for possible reuse. Rinse tank thoroughly with water. If any part of the sealer still remains, repeat steps until old sealant is removed.Rinse tank with water and allow to dry COMPLETELY before using appropriate prep products and Gold Standard Tank Sealer.

Duct Tape works really well.

What is the tank made of? Metal?

yessir

Strip out the old sealer using KBS Strip --> www.kbs-coatings.com/KBS-Strip.html

Then seal up the Tank using the KBS 3-Step Tank Sealer System --> www.kbs-coatings.com/3-Step-Tank-Sealing-System.html

And yes, patch the hole with NuMetal Epoxy Putty before sealing up the tank --> www.kbs-coatings.com/Epoxy-Putty.html

Why should you he is just showing how this system works and steps to take

RustBlast needs to be used at full strength and not diluted. So, it is not necessary for the surface to be bone dry, but you do not want so much water still in the tank that the RustBlast gets diluted. Does that help?

@@Kbscoatings-us yes definitely does, it did wonders but will need to do another pass since I accidentally left the tank outside over night and the condensation from the cold made it rust again. For the sealer it does need to be bone dry correct?

@@rodrigoelizarraraz5557 Yes, before the Tank Sealer, the inside of the tank must be bone dry.

You can let the RustBlast soak on a surface overnight.

This is good to hear! If you have any questions after getting the kit and reading the detailed directions, please feel free to contact us! Thanks for choosing KBS Coatings.

Yes. Clean with KBS Klean, etch with RustBlast and then seal with Tank Sealer.

You can take some heavy plastic and tape it to the inside of the filler neck and then wrap it around the outside of the tank. Also, take your time and be careful. Most customers who seal up their tanks have a beautiful paint job on the exterior of the tank.

Yes, pinholes which are the size of the tip of a pin.

You can also get some mesh to use with the Tank Sealer to seal up the outside of the tank in those trouble areas.

Yes. Please make sure your powder coater keeps the oven less than 500F.

What color is the previous sealer?

It's a pale yellow, probably started out white...

You can get that out with MEK which is available at most paint stores and home improvement stores. After you get it out, you can do the KBS 3-Step Tank Sealing System.

A coaster sized glob was peeled up allowing rust into petcock. I got the chunk of old sealer out but the rest of the tank is still covered in old sealer. Not sure if new sealer would stick to old sealer...

KBS Coatings cool, thank you very much. 10/10 customer service

2 hours of shaking a 15 pound gas tank, and crack cocaine.

He might have a clogged artery or two ! Not good

I bust when i seen this

could be the fumes

Yes, absolutely. Typically this is the kit you would need: www.kbs-coatings.com/large-cycle-tank-sealer-kit.html

Most people use pipe cleaner to keep their pet cock open and remove the pipe cleaners when the Tank Sealer has set up some but not completely. (2 hours is usually ideal).

@@bobbydigital1975 you know it

Pipe cleaners work really well for this. Have you considered pipe cleaners?

@@Kbscoatings-us - Actually that was my first thought. I actually have some. Thanks.
