For knowing how much to sand, use a sharpie marker as a "guide coat" so you can see how much texture you're sanding out. Once the sharpie marker is gone you know it's flat with no texture. This is really helpful on body lines or edges so you know you're not sanding too much.



















Creases on a door that I buffed. Marked them with a sharpie and watched my sanding patter to avoid cutting through the clear in the crease.
