Trying to help a friend out with his car's paint. He got the car repainted about a year or so ago, and was just a single stage paint. The car has no clearcoat, and alot of orange peel everywhere. In the year since its been repainted, the paint has already started flaking off the spoiler, and is looking faded. To try to bring this car back to life, I am thinking I need to wetsand first, then maybe apply a clearcoat? I'm a DIYer like the rest of you guys, so I figured I could just temporarily convert my garage to a paint booth and spray a coat of clear on the car for him, or even try to repaint spoiler if needed, then clear. I'd like some advice on what to do to get the car looking new and shiny, instead of having the reflection of a crayon.
