if you are spraying in acrylic then yes you will have to sand back then primer, base coat, the clear, wet sand, buff and polish...if you are spraying in 2 pak you can just give it a light sand and spray over the original colour then clear, wet sand, buff and polish

if its factory colour it will be 2 pak...start with 400 grit then sand with a 1000 grit...then paint...then clear then wet sand with 1500grit then 2000 grit, buff and polish
