it wont scratch it. especially the 0000 extra fine.

it takes ALOT to scratch glass, I have never ever scratched glass with fine steel wools before, mainly because they dont have the properties to scratch glass.

Factory chrome wont scratch either, however if you are retarded and use something other then 0000 on it, the chrome MIGHT scratch, mainly redips.


Most show cars use 0000 to spot detail at the shows, hard water marks will cease to exist once 0000 is on the job
