After you've got the Coosa installed (assume you're doing this from the outside, the ideal layup is wet-on-wet to get a good chemical bond between each layer. It's much stronger than the bond you'll get if you let each layer cure. . . and, assuming you're using epoxy (which I'd recommend for max bond strength), it'll save you from having to wash off the amine blush and sand down high spots on each layer. This is a job where it's worth recruiting a couple of folks . . one to mix the resin, and one to help handle the cloth . . so you can do it in one session.
