Would like to paint my truck a different color?

first of all its againt the law to paint a truck or car out in the open it has to be done in a spray booth or the epa will get you there is a very big difference painting metal or wood if you want it smooth it has to be blocked [sanded] very time consuming then primer ,wet sanded base coat,clearcoat,color san and clearcoat again so really there is no commonalty between house painting and car painting and the biggest problem with a color change is the door jams under the hood and total engine compartment try maaco or miracle or earl schieb their all pretty cheap go paint a house get paid for it and pay one of those guys to paint your truck
