So I am ready to paint my MT body and I see that the clear body looks bubbly kind of is there some kind of film that's on the body that I have to peel off before painting or is there already a over spray film on the outside I peel of after or what? I tried to see if I can get anything to peel up but I can't get nothing to peel up and I am using a utility knife and cutting at the body and I am getting nothing to come up.
