Are you guys removing the edp coating before prep work on your body panels or leaving it on as the manufacturer suggests. Many tv car shows remove it but don't say why. Advise.
First make sure it's EDP and not a laquer based coating, check with some laquer thinner to make sure. If it is EDP I'd leave it on the backside of the panel but remove it from the exterior surface. I've seen rust under EDP coating, I'd want to make sure you have a known good substrate before you carry on with your prep...at least on anything worth finishing.

Thats good advice. My coating wouldnt come off with any chemical I through at it. So I had to use the DA sander and 80 grit to remove it. I also wanted nice clean metal for the epoxy primer. JRLike Craig says if its the cheap laquer EDP it will rust under it. Just take
a rag and soak it in laquer thinner and let it set for a time. If nothing comes
off its the good stuff and your fine.
And I also remove the EDP on the outside as I just want my paint system
only on the bare metal.
Think of it as a electro-plating using paint solids instead of dissolved metals. When you see it there will be a very thin coating. Ive only seen black. It will be so thin that the metal roughness will be thicker than the coating. Really, you will sand off the coating and hit metal (on a smooth panel) before you hit the bottom of the e-coat thats in the pores of the metal.What exactly is EDP coating? Anyone have a pic of what it looks like? Would my checkered clip have that on it (it has something on it - just not sure what)? -Bob
