For hotcoats we recommend using Resin Research ULTRA Quick Kick Epoxy. The QUICK KICK version is a bit thicker and cures faster therefore provides a thicker hotcoat that stays on the rails better and doesn't drain off due to gravity. A thicker hotcoat will help prevent sanding burnthroughs.
What do you guys think is the best epoxy resin for minimal burn throughs. I have decided I care less about flip time than I do burn throughs. It seems like the hot coat has become my number one enemy since iv started shaping.
We feel that Resin Research Epoxy is the best on the market. This is why we only sell Resin Research, it is a superior product in our opinion.
