New Deck Lid Question
I have a new deck lid for the '85 300D, of course it came from Germany in black primer. Took a few months, there was only one left in the USA warehouse system, and it was dented.
My question is, is this black primer a protective coat that needs to be sanded off before applying a primer/sealer? I remember years ago bodymen sanding the black coating off before applying any primer. Alan

Yeah just sand it a bit so the primer has bite and go about your usual ways. I sand primer up to 2k grit (wet)

Is this E coating a rust preventative? What year did they start applying that?

Cationic e-coat was first introduced in the '70's. On a Lincoln if I remember correctly.
The coating is the main reason why cars do not rust as much as they used to. It was developed by PPG in the late '60's, and it is probably the most brilliant automotive coating ever developed. You do not want to sand it. Like a non-sanding refinish primer, it is full of lead and other heavy metals. I would not sand it at all if possible. Even though it can be glossy, it really needs no sanding to get a primer surfacer to stick. One thing that is important: ecoat is an epoxy and cannot tolerate UV. Keep it out of the sun. I've seen ecoat chaulk in as little as 8 hours. Then you will have adhesion problems.
