Fibreglass tip of the day no 1 - Know Your Catalyst.
Did you know there are speeds of catalyst? In the winter my supplier gives me "fast" catalyst. This is great if its very cold in your garage and you don't want to wait days for your resin to harden... but don't keep it around once the weather gets warm. Get it mixed up and accidentally use it in the summer and you'll find yourself with your brush stuck in a solid pot of just mixed resin ;-)
