Caught me on that one! Newbies can't win - if they ask a question we tell them to search the archives, if they pull up a dead thread, we complain about that, too. At least he asked a new question. As to how many coats, it's up to you. I generally primer and sand between coats until the surface is smooth (all pits filled in.) Then apply color coat until I have full coverage (sanding between coats again to keep things smooth,) then finally clear. The clear adds depth and shininess, so more coats of clear = nicer looking. I've found that most rattle-can jobs are soft regardless of how long they cure.
