Hey Pete ! I certainly agree with Nick, though I don't know if this is your first time using epoxy or not. The first time I used the stuff I was quite surprised at how FAST the stuff seemed to set up (thicken)for me. Though it took about 15 min it sure seemed faster. The next time I used the slow set @ about 65 deg. and liked it ALOT better . I had way longer to fudge with it, the downside being like Nick said it did take about 30 hrs to dry.As I got better at using the epoxy I found I needed less time to apply it. The way I look at it is , I would rather have extra working time and not have to rush things, than to have a lumpy mess that needed to be fixed up later...its up to you either way will work its just a matter of how fast you want to apply the next layer.

Good Luck with your Yak !!
