Is gel-coat difficult to repair?
No. It takes some patience and some thoroughness to generate the best possible finish but that’s pretty much up to you. Basically, you’ll be filling a scratch, gouge chip, or hole with new additional gel-coat and then sanding and polishing to fair it in and bring up the shine. Deep scratches, holes, or chips may require multiple applications of gel-coat but this is not really a time consuming procedure.
