The West System is designed to work in less than ideal conditions. I use it exclusively with the 105 and 106 hardener depending on which cure times I need. In fact I use their whole system glass beads, milled fibers etc. It’s what I used when I was clunking around in wooden boats. Canoes built 20 years ago are still being used on a regular basis. The West System in my book is the best out there for ease of application and finishing.
