The methods talked about here are different than the surface coating you used on the ice chest. Our goal is to get the silicone to impregnate the threads of the material and not just sit on the surface.

I imagine that all consumer silicones are RTV (room temperature vulcanization) since we're not applying heat to turn the product from liquid to solid.
