We need to reseal our windows and some of the screws don't want to come out. My go-to solution is to use an impact driver, but I'm worried about the hammering causing damage to the boat in some way. One the one hand, I want to believe that the wall of the doghouse is strong enough to take a little hammering. On the other hand, I've screwed up a lot of things in my life, and would prefer that this not be one of them. Any thoughts on whether the impact driver will do damage? If so, any thoughts on how to get the screws out?
