Is that marine plywood cut to fit yet? Want to see how your going to bend it for the curvature of the roof. I put down resin first after cleaning the entire surface with acetone then screw her down. With bondo I filled in the edge cracks and voids then released the screw after it was cured. The plywood stayed put and I glasses over it. You have a whole roof your doing and keeping it down might be near impossible unless you cut lines in it to give it some flexibility so it will lay down flat on the roof. Don't want that flinging back up and delaminating from the underside of your pilot house. Giving you a heads up hopefully everyone will join in on this topic and give there opinion to to point you in the right directions. Census is that's how I do it.
