Interior body paint questions

IMHO

Unless you are doing a Concourse restoration I would be sure to cover everything with primer and topcoat.



My dart doesn't have any paint or primer under the dash so it is just surface rust from the factory.

As for color, the visable parts on mine are 80% gloss black, (or something like that) and body color for the rest.

My recollection is they dipped the cars to just about the top of the doors in a primer tank. Who cares about the inside of the roof or A pillers or top of the quarters (designed obsolescents)

If I had my way I would submurge the entire body in a tank and rotate it 360 deg a few times to get every surface inside and out coated with rust inhibitor / primer. And drill holes on sealed panels so it can get in there too.
