It's identical to polyester - just use epoxy resin instead of sun-cure poly.
Rough up the area, then smear on the epoxy, and sand smooth after it's set.
The key thing with epoxy is that it needs to be mixed well, and at the correct hardener/base ratio otherwise it won't set.
Also it's bad for your hands.

Basically polyester is idiot proof to use and it goes off in minutes in the warm sun. I prefer especially when ding repairing as i can be back in the water 30 mins after a fairly serious ding whereas epoxy even when mixed right takes much much longer to reach a sensible hardness by which you can sand it.

Verde wrote:Getting the mix right with epoxy should be really easy. Unlike polyester resins epoxy resins have a set resin to hardener ratio, most commonly it is 1:1 or 2:1. The most important part is to MIX THOROUGHLY. You should mix for at least 4-5 minutes and make sure to "fold" it in on its self. If mixed to vigorously epoxy is prone to forming tiny bubbles, which shouldn't affect strength, but will look ugly. Also according to Resin Research, epoxy is 1/50th as toxic as polyester. I love epoxy and I think its the way forward

A thought "if you can fake sincerity you've got it made"
Plastics are a good chance , even better if they can come from recycling, the fashion needs to over white under whatever coatings.
