Being that these are new car inventory, definitely do not want to leave scrathes. @Fuddlecupz what brush did you use?
@AdamPWC I wonder what the foaming brushes at the self serve car washes are made with. Could it be boars hair? I’m going to check Kleen-rite.com they are a car wash and pressure wash supply company.
Update:
So the foaming brushes that are used to scrub heavy grime and dirt at the self serve car washes are made from Boar’s Hair. So this makes me wonder if using a full Boar’s Hair tucker brush would be possible without causing scratches.
