What brand hat does Richard Petty wear?

I am sure that he possibly wore different sunglasses than the ones in this ad. I have been searching a long time online and this is the only reference with any kind of supported evidence that I have found so far.

I would add that they look like Cool-Ray Polaroid style 300 "Roadmaster" sunglasses. He must have a huge stash of them somewhere, since they always look fresh and they haven't made them since the 70's.
