Review on Clear 100% Silicone Waterproof Caulk & Seal 2.8Oz Squeeze Tube (Pack Of 1) by Dan Venegas

High quality reusable silicone sealant.

Works well, and the fact that it has a cap to keep it sealed is great for when you just need a little bit but don't want to waste an entire tube. I do recommend cleaning out the tip with a wood skewer or something of the sort when you're done before you put it away, though.
