I have a 1986 C22 and one of the windows leaks. The 1986 model does not have the window with the extruded trim like earlier models. It is a piece of Lexan (I think) screwed directly to the outside of the cabin with what appears to be a thin rubber gasket. Are there replacement gaskets or do I put down a bead of marine silicon? Any guidance is appreciated. Thank you to the folks who helped with my steering in reverse question! Randy p.s. I would have tried the use the archives on this but the archives haven't been working lately.
