I have two garage queens, or metal mistresses, as the wife refers to them. Old Cadillacs; one is an all-original 26k time capsule with 60 year old original black lacquer; the other was repainted a few years ago with modern 2 stage paint. Both are garaged and come out only for local shows (assuming we ever have those again) and occasional cruising. I typically give them a thorough detailing every spring, before the season starts, and touched up with spray detailer and maybe a coat of wax, the shine lasts until the next spring, although this year, for various reasons, including moving and the pandemic, I have yet to do the "spring detail." I`ve been happy with the regimen I`ve been using- waterless wash and M07 followed by Souverain on the black lacquer, and waterless wash, Klasse AOI followed by 2 coats of Klasse SG and a coat of Souverain on the newer paint. Does anybody want to try and sell me on switching to a ceramic product? If so, which one? Keep in mind that the original lacquer is thin in places, and I am really trying to avoid unnecessary abrasion on that car.
