Painting your cars hidden areas

Posted by Jerry On 2021/5/26 10:33:09

When painting your cars, what was the original color for the under body area, the back side of fenders, the back side of the hood side panels and the inside floor and cowl?
I have seem them painted black and I have seen them painted the main body color.
On my 42 it looks like the cowl was originally a reddish primer under the cowl pad and bare steel up under and behind the dash

Any thoughts
Thanks
