QuoteThis is me and my son's project kar trying to keep as org as possible,....................
Ok ... had the car been redone before? IF not was the original floor pan/undercarriage color visible?
If not then when and where was the car assemblied?
Answers will lead to what color the car original was an what color you need to return it to.
From there other can offer what they are using (as for type and brand of paint) but IMHO I would use an epoxy primer/sealer toned to match the original color for your car rather than deal with trying to get base coat/clear coat right for this application. Even on cars using that paint process on the body we are still using straight enamels for overspray in the wheelwells and on the undercarriage
