So I've been cleaning the underside of the 67 body for the last couple of days. Basically just scraping off the greese/oil and road grime so far. It almost looks like it's got the trunk paint rather than any kind of undercoat. Not sure what kind of finish I want to put on there when I get to it. Chassis black, rubber bed liner type spray or try to copy the original color/finish( not sure I can find it).
