Caulk

Very important to caulk windows every few years especially basement windows in Chicagoland area with snow and often rain coming up to window. This caulk is strong. A friends daughter got mold in house from house not being sealed good. Good price and in end saves money.

Dap Silicone

Very Strong. I use it to make a sheet metal box air tight. [This review was collected as part of a promotion.]
