  1. So can you actually paint over the epoxy once it has dried? IE if you were painting a bare steel chassis or something in multiple sessions?
    Let's say you 80 grit the bare steel. Prepare it. Epoxy it. Leave it to dry for say a few weeks while you're working on other bits of the car. Can you then sand that epoxy and put paint over it with base and clear, or paint it even with no sanding first? Or, do you HAVE to put a urethane primer over it first? This is where I fall over on my understanding, because of when people use epoxy as SEALER, and paint straight over it during its flash time without sanding it (something I imagine you could NOT do if it has actually completely dried)?

  3. I use proform self etching primer on plastic everyone says you can't do that I do and I did the plastic mirrors on my personal daily drive five years ago and still look as good as the day I did them I use self etching on alot of stuff 🤙 I do also use epoxy on certain stuff aswell I just purposely do self etching primer on plastic just to piss of the idiot's that say you can't do that 🤙

  4. Yes and no. Epoxy doesn't etch into metal, etch primer does, hence the name. If you are sanding or stripping to bare metal, do your first layer in etch primer and then a layer of epoxy. Even when you are doing rust repairs for windscreens the 3m shop always gives you etch primer and 2K paint.

  5. Those 2 are like the old car salesman days putting the special wax on your car all you need to do is prep the surface to be primered correctly and follow the directions for mixing and spraying don't waiste your money

  6. I purchased a Capri rolling shell 12 months ago. It had been sand blasted back to bare metal, rust removed and then primed. I assume it was an epoxy primer. How do I tell? Secondly if it was an epoxy primer how long can it go without a base coat? I’m concerned I may have to strip back down to metal.

  7. I believe you need to understand corrosion is not just rust AS YOU SAY IT, I disagree and yes ALUMINIUM suffers corrosion.
    It's actually OXIDATION. It's white and needs sandpaper or an acidic bath to remove. JUST LIKE RUST.

  8. Well I learnt things that others had showed me and now I know why they failed , always know that etch prime absorbs water but was told it was right primer for the job, etch primer on steel should never be wet rubed before base paint , this can cause paint rise and bubbles and moisture expands

  9. Out of curiosity what is your opinion on the Wattyl Super Etch Epoxy primer? A local panel beater (in Australia) pointed me to it for respraying a 96 GMC truck cab, which would be mild steel. Is this a 'best of both worlds' product or something else?

  10. If you use epoxy, dp90lf anyway, plan on putting filler over every spot of primed surface. Ends up looking like undercoating. Gonna have to sand it all off and start over seems to be the best option.

  11. Hey mate, great video and helpful information as its my first time painting over metal. I had to strip surface rust in some places and im left with some bare metal spots in my engine bay. What do you think of epotec 408 epoxy?
    2-3 coats of Epotec 408
    1-2 coats of wow
    base and clear
    Or if you have a better process would be helpful!
    Cheers mate
