I have read it is almond for the color and GE Silicone Caulk II. Many say kitchen/bath version and it is fine but I would think UV rays and temperature changes would be an issue. I had always been told to use the window/door version outside. But I do see the benefits of having it with mold prevention. Do all still agree that kitchen/bath Silicone II Almond is the correct way to go?
This is a really good question and I have to admit, I didn't know the answer. So I went to the GE site and read about all the different silicone caulks. It looks like the two major differences between Silicone I and II window and Silicone I & II bath is that bath has a mildewcide and Window cures faster. For outside work where there might be rain the future, Window is prefer ed.
So for the boat, on things that may get wet and stay wet, I would probably go for the Bath variety. Note that GE states that no silicone caulk is intended for submersion or constant water. There also seems to be a new caulk, GE Silicone II KB supreme which has the features of both, fast cure and mildew resistant. I would probably use that if available.
All that said for deck plate sealing , deck panels etc, some folks use black silicone. You have to apply neatly using masking tape to get nice lines but the up side is that it doesn't show dirt or mildew since it is already black!
