We are replacing the solid side windows on our Catalina 30. What is the best material to seat the new windows?
We have frameless windows. What is the recommended thickness for the window?
Absolutely down 795. Comes in colors. Once open the tube use it all as will cure on you overnight. Great how to article on Sail magazine web site. I followed their advice and posted it somewhere on this site a few years ago. 3m vhb tape was also useful to hold plexiglass in place will 795 cured.
I did this project a couple years ago, following the procedure demonstrated video (link below). My portlights leaked and a PO had made a mess using hardware store silicone, which was a pain to remove. I also used 3m vhb (very high bond) tape and Dow 795 as mentioned by njlarry (and in video link provided below). I was very pleased with the outcome. No more leaks and looks great. My portlights are tinted very dark and had a few little nicks and imperfections along the edges so by using black 795 the result was a clean and professional look. Good luck and take your time. Like a lot of boat projects its all about adequate preparation and using the correct materials.
