Topsides repair
It's not always necessary to use West epoxy when other materials will accomplish the same end. I use West for a number of different repairs, but will also use 3M Premium Marine Filler, or Interlux Water-tite for filling gouges, scratches etc. The 3M is a vinylester filler and the Water-tite is an epoxy filler. They mix and apply easily, dry much quicker than West, sand easy, and allow you to progress faster on a repair. They're also cheaper to purchase a small amount. Good luck with your repairs.
