Why Should You Use Epoxy Primer? | The Secret to a Long Lasting Paint Job! 

A good epoxy seals the metal like a chemical plastic wrap. It bonds to 80 grit, sealing from moisture. 2k primer, body filler all absorb water, so no wet sanding. Shoot your high-build, sand with acrylic blocks, apply filler after metal work. If grinding to bare metal to stud weld, re-apply spot epoxy. Then filler, glaze, primer to perfection. Apply epoxy when paint ready and paint. Spray 3 coats of inter-coat clear often called flow coat but actually double clear. Wet sand with 1k, 1,3k and clean. Now comes 2-3 coats of European style clear called high solids. Then sit aside for a week to allow inter-coat to shrink & off gas as it shrinks before wet sanding. Once high solids is sprayed, it may not need more than buffing. You are done! Remember, additives for "UV" a, b & c proactive chemical package rises to the top! Wet sanding removes this protection. This is why a double clear or "Flow Coat" is desirable. Buffing does not remove UV protection. My best long term shine comes from no sanding just buffing. And wait 30+ days before adding a ceramic coating. Like concrete, the clear has to cure by off-gassing and shrinking. High solids clear shrinks less, leaving little or no orange peel as it off-gasses leaving a tough deep clear finish. This how Ryan Evan's does it at Counts Kustom's and many others. Extra time, more material, charge for it, but enjoy the results. DK, Retired; ASE Master tech since 78.

Our man Fred is back with another painting video, his sense of humour is well needed on a monday afternoon, thanks Fred

I was really surprised to hear about the pot life on epoxy primer. I’m used to things setting up so quickly that this seems like less pressure to get something sprayed. Good call on the material data sheet. Too many people these days don’t bother to read any instructions and then wonder why things don’t last. This is true not for just paint but all sorts of materials. Thanks for another great video!!

As someone looking to repaint my truck for the first time, it's helpful to hear that you can stack another primer on top of the epoxy. Thanks for the info.

SPI products are high quality ! Just finished using there products on a engine bay . Highly recommend. Customer service is spot on .

I know epoxy primers and paint are used on boats. Always figured if it's good enough for a boat it should be stellar for a car. Fred's confirmation makes the idea credible! 👍

So very cool to see the project coming together! Excellent work and thanks for the tech explanation.

Always enjoy your paint job videos - explained so well. 🙂

Thank you for sharing your knowledge and experience with us!

Gotta see more videos on this 944! This is a job mine is needing soon so that would be great motivation!

Fantastic advice, thank you Fred , I’ll be using your advise on my next project 👍

SPI is my go to primer. Love it. Great video

New DIY subscriber here with ProLite guns, great informative video!!! Great job with all the in-depth details, very valuable since I need it. I look forward to more videos from these guys!

Interesting video, like your presentation style.

Too many people skimp on the prep work and it shows.

all right, brother. was going to do a budget paint job on my e30, but you've convinced me to order some SPI =)

Hello Fred😉👌 from some weird reason, I don't get notifications from your channel... Are you guys still making content on RU-vid?? BTW, Great video😊

Using SPI epoxy primer on an aircraft I’m building, 2k urethane sealer over and a single stage paint , he is right on on all the excellent working aspects of epoxy.

I'm an old guy that learned with nitro-celious lacquer in a Binks gun. This stuff makes an incredible foundation for a really good job.

Did not know there was a difference between Epoxy and 2K. I used 2k about 13 years ago on the car roof and all of a sudden, catastrophic paint failure down to the metal. I will use epoxy this time. Lots of good info for me.

Good vid !

What particular degreaser do you recommend after sanding before applying epoxy primer? Also, when sanding the rust off the metal, do you recommend finishing it off with a fine high grit sand paper to get it ultra smooth or it’s not necessary? Thanks!

Solid points !!!!

Gave it 45 seconds then couldn't take it.

You spray SPI 2k primer over the SPI epoxy primer? Was it the High Build Primer? I enjoyed the Video Thanks

Nice! Great work.

hey great video. I've a question. Could I use heat to reduce flash time? and what temperature I should to use?

Subscribed and Liked.... but I'm definitely not gonna comment!!

I've used the SPI epoxy for a few projects. Great products! What about when you burn through the primer and need to put on another coat before you spray high build? Do you go back down to 80 grit on the bare metal spots?

killer brah

Your channel rocks!!!!!

👍🙂

can you put on on before bondi

👍👊

Epoxy....yay! I almost gave in to the....Epoxy nays.

How long can a car stay outside in just epoxy?

Why not a acid etch primer

Right?

I hear George Costanza could have used less shrinkage

Is this primer better than Eastwood's primer

i'm glad your shirt has your name- that way you won't wear other peoples clothes

You've got good content. Please stop with the silliness.

This is like a kiddie show, a little too childish for me. I dont understand why these guys do that nonsense i assume the majority of us are grown men and would like to be spoken to like grown men.

A 944 is also galvanized steel. That should last forever :)

Why so much filler on the fenders of the 944?
