Thanks guys.
No I doesn't flake and since I did it under where you would paint the scratches won't even show up and since is a sharpie it could get wet and not peal..
Look at the pics with the Ford body. I got tired of Wateing on my F650 stickers and took the sharpie and did the grill lights door handles and also I gave it a name lol. It's called the angry lil bee.
