Two questions for people with knowledge or experience with the UV
curing polyester resins:

1) Are they (any of them) compatible with polystyrene foam?

2) Once the UV light has initiated the polymerization, will it spread
through the
layup even into places where the light did not penetrate? I'm
thinking, for instance
about the underside of carbon fiber cloth.

Thanks.

Might post this on boats.building.
