Whether your motorcycle is a Harley-Davidson or a Ducati, or any number of bikes in between, there's one horror that is always on your mind: The dreaded paint scratch. Depending on the severity of your scratch or gouge, it can be repaired to look as good as new using a few items found in your local hardware store.
Using a clean rag, apply dark shoe polish over the affected areas. This will bring out the obvious scratches, as well as any that might not be as deep or wide.
Block sand the scratches, but use copious amounts of water when sanding. This reduces the scratches and will allow for an easier reduction in scratches later on in the process.
Liberally apply rubbing compound to the newly-sanded area so as to cover any and all existing scratches or gouges completely.
Lightly buff the rubbing compound using your polishing wheel. It is crucial that you don't set the speed too high, as increased RPMs can buff through to the next layer of paint.
Using another dry, clean rag, hand buff the remainder of the rubbing compound around the scratched area. Finish off the area by applying car wax and buffing it out with a clean, dry rag.
There might be times when your motorcycle shows a "scratch" that is actually rubber or paint from another vehicle touching your motorcycle's paint job. To easily remove these blemishes, simply rub the area with adhesive remover or acetone on a soft, dry rag.
