How to Fiberglass Anything 

With so many people passing through It Would be pretty cool to know where your all from let me know down here.

Just blagged my way into a boat building job by telling them I had experience with fibreglass. I haven’t, so this helped a lot lol. Cheers bro

I'm late to the party, I know, but just I wanted to relay my heartfelt thank you for your videos. I've new (actually 75 years old) to fiberglassing, outboard engine steering and controls installations and such; but you've made videos that take the mystic out of these tasks. Thank you again!!

It's best to paint on a layer of resin first and letting it dry before adding the glass because the plywood will soak up a lot of resin. If you don't, you won't get as good a bond as you think and it can delaminate down the track. Also, if you are glassing over an outside corner, you will have the same bonding issue you have on an inside corner, so it's best to round the corners off with a router :)

There's a bit of talent involved in getting the right amount of resin down before the glass is placed, then getting just the right amount of resin into the top of the material, and then, if you are going to do a lay-up with woven roving, add more resin and apply the roving. Wet that out without over saturating the material. All the strength is in the material, not the resin, and too much resin actually weakens the layup. Once glass sets up, it needs to be "wiped off" with sandpaper to prevent air bubbles between the layups caused by "stickers".. Good glass is clear. A bad spot needs to be ground out and reglassed. Fiberglass is flexable because the strands are so tiny, and , yes, it is actually glass. A lot of the diy articles use epoxy resin, but ALL commercial projects are done in polyester resin. Too much hardener will make glass brittle as it ages or turn brown even when new. The enemy of fiberglass is sun light. Keep it protected (coated with something), and it will last many years. Originally, fiberglass resin was cured using sunlight, which is why all the fiberglass boats came from Florida for years. Don't try this though, just use the hardener. Unprotected fiberglass will continue to harden and then crack. If glassing over wood, wipe the surface off with sandpaper, then a barely moist cloth and coat it with resin... Allow it to harden, then wipe it again. Resand very lightly if needed and run the tack rag again. A really great filler can be made super cheap using CaCO3 (calcium carbonate) and resin. It really helps with inside corners and bad spots in cheap plywood like knotholes without affecting quality or strength. . .

Brilliant. Those dogs sounded like air raid sirens going off-great watchdogs.

Very simple nice example, enough to encourage anyone to try it. Recently bought a an older 19'8" Carolina Skiff which has a huge stern standing platform(easily 4'*7' beam with two 40 gallon plus bait wells. Its too large, no walking space behind the console seating. Since I rarely use the bait wells I am shortening the platform front to back distance and converting same bait well space to two seats for passengers, where the middle will become one bait well. Great motivating video!

Thanks so much for the video! Considering building some speaker boxes out of fiberglass, and this was a super comprehensive look at what I’m up against! Thanks 🙏🏼

Hey mate, great video! I'm doing my first fibre glassing project and this gave me a lot of good tips.

I was looking up fiberglass info and saw you had a video. I had to check yours out of course! Very helpful, thanks for posting it 👍

Useful ideas esp simple caulk for filets, tearing not cutting, putting all the layers down before rolling. It would be interesting to hear abour polyester vs. epoxy, cleanup. thanks!

Hey mate, just come across this video thanks for the tips. Did you gelcoat over that also? You should do another video and show how it's going or you using it 👍

Thanks a bunch for your video. It's nice to see some one show the mixing ratio. To actually see it, and tearing verses cutting the cloth. Excellent!!!! And I'm from Omaha, Nebraska

Cool tutorials man, keep it up

Thanks for making it so simple to understand without using so many technical terms, im literally gonna try fibreglsss the bulkheads in my boat because of your video Thanks brother 🙏

Excellent stuff. Thank you for making this!

Love these tutorials of yours bro

Nice video. That said, always pre coat the surface you are glassing or it will suck the resin from the glass. Also, heave resin application is not a good idea and leads to weak layups. Just enough resin to soak the glass. Inside that box there is no way to get the extra resin out and it will pool creating an uneven surface.

Thanks for the basics, easy to understand and worth the watch..from Queensland Australia

You sound just like Korg. That’s a good thing.

thanks for your video its being really helpful

Thank you. I’m going to be making an instrument package for a 2021 Yamaha Jet boat. There isn’t enough room for the Chartplotter so this will move my gauges around to make room. I’ll be layering the fiberglass over a plastic mock up. Here’s hoping it goes well.

Good work man, thinking of building a live bait tank for my live baits. 👍

Thanks for the video 👍 the dogs scared me shitless on the 7 minute mark 😂

Nice Job. Thanks for making this video.

Great video, about to patch some spots on my skoolie Greetings from Arizona

You’re amazing thank you

great video i learned fb making from u . u make it simple.

handling the fiberglass with ur bare hands!!! brave man...

I am building a diving board: -The Base is made of Maple and Douglas Fir Ply wood, 4 sheets thick glued together. Dimensions are 2''x1',4''X14' -I am planing on applying mat fiberglass to the finished product to add strength and protect the board from the elements. Would Mat Fiber glass be ideal for this application if not, please let me know which type of fiberglass you would Recommend.

Great video! Why don’t you fibre the top lips of the box, wouldn’t that allow water to find its way in and rot the wood eventually?

Very usefull! Thank you!

Thanks!

Hello from Alaska :) Thanks for all the info you put in the video! Its going to help a lot. Your dogs are awesome lol. I loved the mid-video husky howling intermission. Your fish box is shaped very much like the bathtub I'm making. Its a sort of funny shape with a hard to reach compartment at the foot. I didn't hear you mention it, but when you are sanding fiberglass, I've heard always wear a respirator :) -Steph

Great how-to. Thanks 👏👊👍

Nice and informative video, how will be the mechanical strength of the product and what are the chemicals have been used to make this.

Short and sweet, Well done

A good starter tutorial for sure, definitely not complaining haha. But I wanna redo my 1980 celica's door panels, I can't find any replacement parts that aren't stupid expensive. Do you think if I did that but made a wire frame and then fibeeglassed over it (with a good backing for the body) it would work? And howd your boat go?

How expensive is the materials like 5 gal of the resin and 1 gallon of catalyst and the fiber?

Thanks for the video.

If I was now for example to fibreglass a complete vehicle fender. How will I be able to smooth it out? Is their a certain filler needed.

Absolute legend

sir, I have a question if you dont mind giving me an important tip. I have a concrete water slide in my swimming pool and it is not slippery as we want it to be. We are thinking of overlaying a fiberglass on top of the concrete. will it work just exactly how you applied it on your video? tHANK you in advance.

I just need about 20 square foot of that fabric do they come in different thicknesses because I'm trying to replace some holes in a old garage door paneling. THANKS FROM MARYLAND USA

Thanks so much

HI That box should have been sealed with resin first. as it will soak up a heap of resin, till it gets to the core. then when dry, you can add the FG at will and make it solid as

this was amazing!!!!!

Am i the only one that feels like i cant expose an inch of skin or ill be itchy for days? How is this man on a picnic table in his back yard with just gloves and a mask?

Thanks

Good video can you confirm how many layers and what gsm matting one would use to make a box like that 100% waterproof and be able to hold water in form of a storage tank. Your help would be appreciated. Thanks

Just curious to why you fiberglass’s the box? I have a 1966 Impala and it’s rusted around where the windshield goes so ima fiberglass the holes Anyways thx for the video

Cool thank you

Was that box being used as a mold or was the application of fiberglass just to strengthen and possibly add some water resistance?

Bloody good video mate. Thanks for the help.

i was going to make box with a lid to go in my caravan ,as another chiller box.Should i use the chop mat you used ,cheers and thanks

Show the finished box - did you paint it? Coat it? What was that process like?

Great video brother, where do u get your chemicals from??

How do you get the fiberglass out.

I am a resident of Nashville. I'm curious as-to what is the benefit of fiberglassing the inside of a box such as that is? Waterproofing? It's a nice box , as I said , I'm just curious about it's functionality. Nice instructional video! take it easy!😉

Great video 👍👍👍👏👏

Thank you from Ethiopia

Just curious: are you fiberglassing the box to make it waterproof or?

Hi. I just stumbled onto your channel and saw this video. Is there some sort of chemical that is supposed to be used after after this video like a resin to close up pores or something?

Thanks from the USA.

hi thanks for the vid :) I was wondering if I could you this method to strengthen my gazebo poles. What do you think? I was also thinking to wrap duct tape round them first. Thanks again

good tips for us beginners, thankyou.

6:59 did a firetruck go by? lol

Dude, best random find this year. I've always wondered how fiberglass went down.... is this the basic format for all fiberglass? And I couldn't tell, does it come out crystal clear or can you see the fiberglass? Sorry for basic questions. Great video. Will subscribe for sho

Nice Job! I wonder what kind of fruit was laying on the ground ;)

Hello, Gabriel here from AL, I will like to know where did you buy the big roll of fiberglasss>

Nice job on the video!

Queensland, Prison Island here ;) Cheers for the vid. Trying to figure out how to lay a coat over the side of my 4x4... remove it and fit it to the camper.. same body shell.

Doesn't the fiberglass make you itchy? Great vid Tks 👌🏻

Nice job. Did you end up putting any type of gel coat over the resin and matting?

I had a huge hole in my box but I fixed it by jamming some caulk in it. Maybe you need some African style caulk for your box.

Bro if you say ratios in moles and use volume to mix you have to watch for the density of both parts. But nice video :)

Awesome

I love the dog lol

What about the exposed plywood edges? How do you glass those?

I have never roller will a card work? I have a small paint roller from dollar tree will it work? Please help me. First time to do fiberglass. Gonna apply it straght to door metal and walls wood cedar will it stick? Trying to get hurricane proof.

I LOVE YOUR DOGS!!! 💕🐶💕🐶💕

Liked!

Nice work thinking about making a spoiler for mu car

Cool

what the best way to fiber glass cardborad

Nice Job,

i wish you'd mentioned this wasn't a mould as the caulking threw me off. i was thinking why didn't you use 'peanut butter'? why didn't you use resin first? but, now i see what your intent was....

Hello there I'm very new to all this where would I buy the fiberglass glass Fabric and resin from? Also what does the Catalyst do do you need to pour that in the resin?

Great video !! 😃🤗👍💃🏻👍👍

Great job, hi from England 👍

Good job sir keep it up

I work at a fiberglass plant and the only thing I like about it is, mixing chemicals. Lol It makes me feel like a scientist.

Sir I like this work

i work for a boat yard and am having a hard time with the Epoxy resin fibre layout. truth be told i cant get the right calculation or say my layout looks powdery at the base of the lamination. can you help me out will be grateful with your help

Whats the white cloth looks like call???

Nice

What items do you use?

the resin u r using is blue colour..... can u tel me what is that

ok so the fist full of fiber strands is normal. I always end up with it everywhere tools etc, but looks pretty normal

Sir, can you send me the materials you used.?
