Cosmetic Hull scratches repair

I'm trying to repair some hull gouges scratches. What is the best way to take care of...Please refer me to any FAQ if they are posted.

I have had good luck using Marine Tex. It is an epoxy resin that come in white. Clean the scratches, mix up the epoxy, squeege it on. If you finish with a wipe of a wet finger it will give the epoxy a very smooth finish. The hardened epoxy can be sanded.
