Analyze your existing paint. The first step before determining if a budget paint job will work on your Mustang is to assess the current condition of the paint. In many cases you can prep and paint directly over an existing paint job, but only if it's in solid shape.
At a minimum you want to remove all the chrome from the car. Take off both front and rear bumpers. If your Mustang has bumperettes that are body color be sure to bring them along so they can get sprayed at the same time as the rest of the car. Remove all rocker, hood and trunk molding. Same for wheel well molding and all emblems. This would be a good time to order some new emblems and attachment hardware. Also spend some time cleaning up all the chrome with #0000 steel wool. Nothing looks worse on a fresh paint job then faded emblems and corroded, cloudy chrome.
Satin or silk - Water-based vinyl or acrylic paint for walls in high-wear areas, such as hallways and kitchens. A satin finish will be slightly shinier than silk.
