[Public-list] Lexan or Acrylic ?

[Bob Crinion]

Hey Stephen,

A friend of mine recommended the Butyl Rubber for this task.
What size/width/thickness/color was the roll of Butyl Rubber?
Placing it in the cooler was a good idea!

The ports in my boat, A30 #560 have this grey stuff as a caulk.
Perhaps it is the original caulking, if so; maybe I should use the same
thing again since it lasted 30 years.
A couple ports leak and I have been band-aiding it for now with silicone
until a permanent fix is possible.


Thanks, and Thanks to George D for the Alberg 30 website write up on the
windows!

Tom,

It is used for commercial windows which can purchased in a roll, I purchased
it from a glass shop that installs auto window and glass. We installed our
ports in the heat of the summer. In order to keep the material workable and
not so sticky, we put it into a cooler. Take it out of the cooler cut the
amount required and install port by port. 

This works great and doesn't cause a mess like silicone or Boat Life. The
other nice option, it stays soft and works with the hull. I haven't had a
leak in years.

Stephen

George,

Thank you for this post! I will file it away for my next window project.

Stephen,

Thanks for the heads up about "butyl rubber". Is this what is used to mount
auto windshields? If so it sounds like a pretty good idea. I for one have
seen far more leaking port lights than I have windshields. Is it available
in colors other that black? Or was that even an issue?
