This may be redundant,I'm sorry,but I did a search and did not get anywhere. I have nos front sheetmetal for my car with the e-coating. I was told that it should be removed for proper paint adhesion, but I said that it should be left on. Me being a novice bodyman, really doesn't know.What is the proper way to prep these panels for paint? Should they be sanded, coated with etching primer or what....Also should the car have primer on it before any body filler, then prime again or does the primer come after all the filling and bodywork is complete..........Thanks in advance :confused:
