well i want to do some fibreglass work starting this weekend/all next week... since its going to be around 30-40F, is it too cold? will the resin be able to dry? or will a heatgun be sufficient?

thanks

it will harden... but it'll take a lont time in that cold... If its just a small bit of fibreglass the heat gun might do, but it's still going to take quite a while to harden. If you could insulate it somehow, it will create its own heat and cure faster.

I wouldnt even try unless you have a heated garage. I doubt it would ever cure properly in -40.

nevermind...just realized that is 30-40f...yeah, its possible. Add more hardener.
