Bob is right, most two part epoxies yellow, some faster than others. I've been using flex coat ultra v for awhile and I'm very happy with the results.I was using devcon but I noticed the yellowing on white/pearl baits and switched. I like the flex coat for two reasons, the uv filters and it's a softer finish so it's more impact resistant than devcon. These are the only two products I can speak about, all I've ever used.
