I use West Systems. In the cold months I always use teh fast hardener and still have plenty of time to do layups.
A great technique taught to me by a local builder (aerolite on these forums) is the following. When you want to do several layers at once, cut pieces of cloth a little larger than you need. Also cut two large pieces of plastic vapour barrier. Smear some epoxy one one of the vapour barrier pieces and lay your wetted cloth down in layers on top of the vapour barrier. After the final layer of cloth, lay the other piece of vapour barrier on top, forming a sandwich, with your layers of cloth between the vapour barrier peices. Then you can use an exacto knife to do very nice cuts of the sandwhich to the exact size/shape you need, without any fraying. Peel off one side of the vapour barrier, lay down the cloth, and then peel off the remaing side of vapour barrier. WOrks great with minimal mess.
