:lol
Thanks for that. Can I assume you have no evidence to support your claim then? I'm not trying to be confrontational, it just seems like everyone who supports the polishing idea has no proof to back it up. Even Ginos own helmets don't back it up.
It's sort of common knowledge, I grew up in the late 1970s and early 1980s and car culture (fixing up old cars) was a big deal back then.
I read about it and many, many car magazines over the years and no, I did not save a magazine that I read 20 years ago to post it here for you.
I'd do your homework for you but honestly I've got more important stuff going on today like my sons Cub Scout Pinewood Derby. I'd encourage you to research auto paint from the 1970s as your schedule allows.
