Materials problem?

I’m thinking about building a board with standard foam, resin, and UV catalyst. Then I’m thinking about using some wood/fiberglass/epoxy fins as glass-ons. Is there any material instability problem between the fully cured epoxy fins and standard board that I need to know about. It seems to me that once every thing is cured, there should be no problem.

Thanks!

Plenty of guys make boards with epoxy resin and Clark blanks.

Wood fins too.
