I will probably end up buying a fast setting epoxy. I have just started to build a tent around the kayak. I'll make it from leftover strips and cords from the ceiling so i can adjust its height. Close to the kayak when it's setting and high when i'm working on it. When it's done, I'll see how much I can heat it and then decide whether to buy the fast or normal setting epoxy.

Insulating the garage is not really an option. It is rented just for building the kayak, and I'll leave it again when the kayak is done. This is also the reason why I don't want to wait for spring to do the glassing. I'll still have to pay the rent.

About amine blush:As I understand it, it is only a problem if I let it cure longer then the stage where is tack-free, but can still be dented with a fingernail (Green stage / chemical bond). In this stage the next coat will dissolve the amine blush. It's only necessary to wash if I let it cure more. Do I get it right???
