Hello friends, we are in the process of replacing floor sections and now are at the point of tracing leaks and repairing them. Here are some pics of the window and previous owners job of sealing, not very impressive to say the least so after removing this material as best I can what do you all recommend to use? I have heard pro silicon and never silicon, so all contributions are appreciated. Also the flooring material debate. Marine grade, treated, non treated, I know sealing the edges is important. Thanking you in advance. Steve & Lori
P.S. It also looks like I will have to remove and rivet a seam at this window. What type of rivets for this? Olympic?
