I've been digging and digging and digging to try to find alternative uc cures.
I found this one most recently:
This has a list of several clears. I e-mailed them about a preferred product for non-yellowing and water resistant. However, you need a high-intensity uv light to make these cure... which are very very expensive. They said a black light or nail light bulb is not intense enough to fully cure (they recommend an 1100 watt light).
I then checked out cureuv.com
This site had guitar finishes that looked great. However, the company said that this isn't intended for outdoor use or being submersed in water.
They recommended a separate product:
However, this is an aerosol. I dug deeper and found this:
Cureuv said that this provides a hard, clear, non-yellowing, gloss finish. He said that they have a client that uses this on surfboars... imagine that! Anyway, I ordered some (more costly than solarez) to try it out.
I found other automotive uv cures, but they were also aerosols... at 40 bucks a Plaster of Paris.
