Factory primer on goodmark fenders

[lime73]

Getting ready to paint mt goodmarks and have heard differing opinions on black primer on them. Some people have told me to strip them first some have told me to scuff and shoot.  What if the general concensus around here?  If scuff and shoot what should i scuff with?

EDP is a pre primer. NO need to strip it off unless it is bubbled in an area. Just scuff and primer. If you call AMD or Goodmakr they will tell you the same thing.

 , there is absolutely no need to remove EDP,unless you're doing concours restoration ,starting with clean bare metal and keeping all same coatings throughout the whole car. Rough it up with red scotch pad and 320 grit paper,coat or two of epoxy,scuff/sand and paint

The EDP coating is fine as long as it has not had prolonged exposure to sunlite.  Sunlite (UV Rays) can cause the EDP coating to degrade.  EDP is also the same as E-Coat.

It has very good adhesion properties to metal and makes for a very good primer.

I agree with the previous opinions above.
