In the past I have used the pre mixed UV sanding resin without any issues. But I am doing a series of boards for friends so I bought a 5 gallon drum of UV cure lam resin from Fiberglass Hawaii. I am using this resin with surfacing agent for the fill and gloss coats. I followed the recommended ratio of SA (yes I shook up the bottle) and used my usual procedure of flashing it in the sun for 30s, bringing it inside for a few minutes, then bringing it back outside to cure fully.
The problem is that when the wax rose to the surface, it did so with a fine texture that didn't provide full coverage. This caused the resin to not cure completely. I actually brushed on a thin layer of SA which allowed it to cure to a sandable surface. But that created a nightmarish thick layer of wax to get through. Is there something I can do to prevent the wax from forming that texture so that it cures properly?
