How long should I wait after painting before I can wetsand and buff out my paint?
You can begin wetsanding the paint after several hours. Some paints harden faster than others. As long as the paint is hard enough to sand, you can begin. I generally let my paint jobs sit overnight before wetsanding and buffing. You can also wait several days, months or even years. The wetsanding and buffing processes become slightly more difficult when the paint gets harder, but not significantly. If you painted an entire vehicle, it will be easier if you wetsand and buff it before you put the trim back on.
