The '31 has been on for about 4 years, and the '36 Chev. has been on 2 yrs. Very easy clean up, that is what I like about it, I get tired of waxing & clean up for Car Shows. Besides that, my Model A was picked at Cruise In, as owners choice, against some pretty nice cars. I was shocked, as I don't care about awards, been there, done that.
