One more question.

My pal shot his 29 A roadster with DP-90 in a mustard-like color.
I don't know why the heck he did that - the color choice - but he did and a year later he was wondering why as well.

Anyway, he sanded that down and shot the roadster with DP-90 in a very dark almost black gray.

Looks good, but I'm wondering how much protection he has from the elements?

So far - about two years down the road for the last primer application - the car hasn't developed any rust bubbles that I can find.

An original body fwiw.
