Ok I have a soccer mom who has a scratch down the side of her car that requires touchup. She has already bought the paint and is wanting me to touch it up. My question is how would I attempt this, apply and hit it up with what? I have the 1z line has far as polishes go so and have a pc. So if I can use what I already have that would be great so I make more profit, ive never done this before but im assuming it cant be that difficult.
