i can completely understand that then! I work in a shop making custom stainlesss kitchens/hood systems/whatever the customer wants shop! So when the stainless comes in it is covered in vinyl, we mainly use 18ga, 16ga and 14ga. In that scenario there is no reason for me to brush it... in fact it would only make my job harder polishing out the scratches lol
