GE SSG4000-24 UltraGlaze Silicone Glazing Sealant, 10.1 fl oz Tube, Black (Case of 24)

I have a very large outside sauna and it is totally encased in glass and this sealant is the only way to get the seal proper in the Caribbean climate with all the heat and humidity. It stays in place and does not shrink under temp and water
