Recommended sealant for replacement Lexan windows..?

[paularey]

Decided I was just going to tear all my old crazed windows out of the Catamaran I’m doing a refurb on and use the old ones for templates to make all new Lexan windows. Just feeling around out there now for a good recommended sealant…? There is such a plethora of sealants available it’s hard to choose sometimes. Off hand I was thinking of the 3M marine sealant but I’m open to suggestions and techniques for application…?
