Cold weather ding repair

I've used West Systems 105 epoxy on hand planes and alaias, and it works really well if you want a super glossy surface. The regular 205 hardener has a slight yellowish tint which is not noticeable when laminating over wood or if applied in a thin layer over paint, but on a surfboard you might want the special 207 hardener which cures clear. The 207 is twice the price of 205 though...

I think marine resins tend to be more expensive than other types of resins. Just less than 3 pints of 105 resin + 205 hardener costs 50% more than 3 pints of RR Kwik Kick. I've read good things about Green Room resin but never tried it.
