... I even believe that Accumulator has said it. The only exceptions I've found to this rule are using ONR properly, and Accumulator's BHB jiggle method. *Most* of the time, ONR won't mar (at least on a visible level). A properly used (and in proper condition) BHB won't mar, either. Other than that.... you touch it, it's gonna mar.
Yeah, no matter who you are or how you touch it, sooner or later you're gonna mar it. IT's just a question of how often/severely you inflict that marring.
BUT...having just gone through a tough winter with a black SUV for my daily dog-hauler (yeah, it's metallic, but I know how to inspect

), if you touch it *properly* you can keep the marring to a minimum. After the quick-lube place incident, I found *three* Random Isolated Shallow Scratches on the Yukon's hood. Only one was over 1" long and all three were clustered together (so I suspect that something stuck to my wash/dry media when I did that area during one wash). That's all the marring on that panel. I was inspecting the vehicle after doing the hood (both incandescent light and bright sunlight, several whole minutes per panel) and none of the other panels is much if any worse (though the one dog did inflict a RI
DS on one spot near a door)...not perfect but not bad if I do say so myself (Accumulator wrecks shoulder patting self on back). After 11 months it wouldn't *need* polishing for anything except some Autopia-level inspection and since the Collinite is still holding up fine I'm not gonna do anything until it really needs done.
So yeah...touching it regularly during the wash/dry (including QD spritz-and-buff while drying) will result in some marring. But over the course of a year it shouldn't be anything major. Just gotta do all that touching in just the right way, every single time.
Black, silver, whatever...clearcoat is clearcoat and marring is marring.
As for marring during the polishing/prep process, that can happen too. Gotta keep the shop spotlessly clean (consider air filtration, etc.) and gotta watch every single contact with any buffing media. No, you usually *cannot* pull the vehicle outside numerous times (say, to check for holograms) without *something* abrasive getting on it. That simply needs to be taken into consideration..how much do you care? Enough to at least ONR a vehicle that appears to be spotless? Enough to BHB/foamgun it? And those will risk marring too. Tough call.
Regarding QDing/etc. at carshows, heh heh...that's one reason why I don't show my cars.
