Start by sanding a test area by laying your block flat on the surface and sliding it left and right a few times then moving down and repeating the pattern.

The idea is to gradually eliminate the coarser scratches from the paint, levelling the paint’s surface with finer and finer scratches that can eventually be hidden with polish.įill a bucket with slightly soapy water and let your sandpaper soak in it for up to an hour before you begin, then wrap it around a soft colour sanding block. Then use wet sanding to start smoothing your surface with the aim of removing the tiny bumps and ripples in the paint that may have occurred at the paint spray gun stage, frequently referred to as orange peel.Īs you sand, you’ll be upping the grade of your sandpaper all the way to micro-fine 3000 grit varieties. Once fully cured you can use a tungsten block to carefully eliminate any of the more prominent nibs of paint of dust before wet sanding.
