ok well, basically from my limited understanding
you'll need sanding sealer first to seal the body, then a primer coat (usually white), then your actual colour, then the clear afterwards
and after a coat of anything you want to do a little sanding with very fine wetsanding paper to get it flat again, and then you may want to put on more coats
i believe the clear usually has between 3 and 10ish coats sometimes plenty more
and the colour paint you just need a few coats until you get a solid enough colour out of it, oh and the sanding sealer, maybe 2 or so? just til you know it's thoroughly sealed
i'm probably wrong, someone correct me
oh, and just let me know any words you didn't understand, i'll try and explain them
