EDP coating/paint prep

I've just finished welding in some replacement panels that were coated at the factory with black EDP coating. I want to prep the panels for painting first with epoxy primer, to be followed by primer and finish coats. My question: what is the proper preparation for the panels coated with EDP--does it need to be entirely removed, scuffed, or what?

Thanks in advance for your help!

Jim

I did some checking around on various web sites and it seems the consensus is that you can shoot epoxy primer over EDP, after scuffing it a bit with a scotchbrite pad. I would also wipe down with wax and grease remover.
Check to be sure it's really EDP by wiping with a lacquer thinner soaked rag. If it comes off, it's not EDP.

If you can take it down to metal, why not take it down to metal. This way you'll know exactly what you have. I recently bought some patch panels for a roadster I'm working on. I noticed, when I sanded the coating off, there was rust underneath. Needless to say, I removed all of the coating and removed the rust.

That's a good option as well. Then you know what's underneath your paint.

Thanks for your replies--I think I'll take them down to metal just to be extra safe.
