I painted cars/truck..for years and a couple transports . Had my own mixing equipment/station PPG paint system. Mostly basecoat clearcoat.
Take it to a good autobody repair shop. You want a good clearcoat on your stock...PPG..RM.... Sherman Williams.... Sikens..DuPont...etc. Make sure they put the flatting agent in it...,that is if you want a flat, clear look.
