Surfboard Resin for Boat Building? (Entropy SuperSap CLR)

I might have access to enough resin to do my whole skiff, but want to make sure that it isn't going to give me any issues. Has anyone used resins that seem to be geared more toward surfboards or wood boats due to the "clear" attribute? I can't imagine it would be detrimental to building boats, but I have no experience.

When comparing to the West System epoxy kits, it looks to be adequate in all areas except Tg, which I'm assuming is glass transition temperature, even though it's not a thermoplastic? I could be interpreting that wrong, since even the West System Tg seems lower than you would want on a boat.

Can anyone offer any advice? I would hate to tell the guy offering it to me that I can use it, but then end up using something else.

Thanks,

As I understand it Tg is the temperature where it begins to lose strength, starts to soften. If so, 102F seems pretty low for a boat in a warm area, or where it would be exposed to direct sun. I’d consider using it where I am (Alaska), but probably not in South Carolina.

But maybe I’m interpreting that incorrectly. No doubt someone here can give a more informed answer.

 

Doing a post cure at an elevated temperature may improve the final Tg. Support the structure so it wont twist, cover with black plastic in direct sunlight for a few days.....
