For repairing non-structural damage, the most basic steps include cleaning and roughing up the surface with a grinder and/or 60-80 grit sandpaper, then cleaning the surface again with alcohol or acetone. Shallow damage to the gelcoat can be repaired with body filler.
If the chips are visible, cosmetic in nature, there is work involved in achieving a visually appealing result. This involves filling and sanding with finer and finer grit sandpaper, then applying matching
paint or gelcoat.
