Epoxy over old paint

B

Bill

Do the panels have to be bare metal before applying epoxy. Most of the car won't be stripped to bare metal just da, so will the epoxy adhere to the sanded paint. Also wnted to spray the undersde of car without completely stripping it. Help me out as I want to spray it this week.
 
No the panels dont have to be in bare metal to apply the epoxy over.. We suggest bare metal however so you know what you are starting with from scratch.. The job is only as good as the foundation, just like your home and you may spend thousands of dollars on materials.. so its cheap insurance to strip to bare metal..
Doesnt take that long and you know exactly what is there..

For example.. Not too long ago I took in a car for a repaint.. Only had one paint job on it.. Was stripped 15 years ago and was a garage queen.. Ended up with panels needing replacement etc.. So when I started stripping adjacent panels to those i had replaced, what did I find....... Rust... Would not have found that, if I trusted the other paint job..

So let me put it like this.. Epoxy is the best thing you can put over a substrate of any kind to build off of.. It is however best when used over bare metal to ensure the best possible end result!!!


As for the underside.. strip what you want here again and seal it all with epoxy... Make sure the underside is de greased and washed,.,. and all areas you want ot epoxy scuffed..

Same rule applys here as well,, You dont have to strip it, but it would be best to konw what you are starting with


Hope that answers your question
 
i will be repainting edwards 37 next month. will block wet with 180 the seal with epoxy. i use the epoxy as a barrier coat to paint on .

Did a 68 nova a while back. Original paint....i believe back then was acrylic laquer? Was sanded down, and all imperfections removed, and couple coats of epoxy applied over it..then 2k primer. SS red with clear over top. Now this is not recommended in anyway for a top quality job, but the car is for the owners son who was just about the graduate college and his first muscle car, so you could imagine the consequences to doing a bare metal top not job. It's not going to last forever and the owner knows. So far the epoxy has held everything down nicely. Went through the hot summer sun here just fine. Moral of the story...you cant beat epoxy as a barrier coat as shine has said.
