What do you fellas mean by 'suede' paint? Are you referring to a 'flat' or 'semi-flat' finish? with ie. low light reflection?
I don't think I've ever heard the 'suede' term used previously (in 45 yrs or so) referring to automotive finishes. Are there GM documents that use the suede term re '69 camaros??
I do recall when I purchased my '69 Camaro in '76, the first time I cleaned my rear glass on the inside, I *noticed* that the paint on the lower garnish moulding was more flat than anything I'd seen previously on a car I'd owned. That same car has been sitting in my basement garage since 1980, and I don'[t recall 'cleaning' the inside of the back glass in that time.. if I have, it's only been once or twice..

so it should still be close to the same. I've pushed the car out a half dozen times in those 30+ year since to wash it on the outside.. and wiped it down on the inside maybe 2 or 3 times. I can take a photo tonight if it would halp, but I can't guarantee the light level..?
