Take a brand new razor blade and carefully round off the edges slightly by rubbing them on pavement.Then slowly work the blade under the peeling paint,being careful not to gouge the remaining undercoat.
sand paper and a sander best way
take it to a carwash where you wash your own car. hit it with the high pressure wands. good to go
