Hello
I saw some paint jobs on tv shows like overhaulin and stuff like that where they do cars with 2 3 4 colours.. and they use tape to mask the cars and after they remove the tape it looks fantastic, really perfect. i try to do the same in some cars and it's never perfect.
Whats the trick? You have to remove the tape with tha paint still wet, you have to wait for it to dry complete? it's the tape that it's special and don't let paint goes under it?

Anyone to explain this
