The portlight in one of the cabins was leaking pretty bad if it rained hard....so we started searching for the material. We found the gasket material at a marine supply in St. Maarten - couldn't find it in the US!
We removed the window from the porthole.
Closeup of the gasket....no wonder it leaked!!
Cleaned up the plexiglass and removed all the old glue with denatured alcohol.
Painted the glue on the pre-measured and cut, new gasket.
Once everything was just the right amount of tacky....carefully placed the new gasket in the groove.
All done and ready to install.
Installed and water tight!!
