I am happy with the sealant
I am happy with the sealant. It dries to a rubbery fell and adheres well to all my roofing materials. Only time will tell if it holds up well. I cleaned up with mineral spirits which worked well.

Wear gloves and make sure to not get it on an area you don't want it!
Used this product for years never had an issue when installed correctly. Stays flexible forever great for areas where areas have expansion or some movement.

It seemed to work. I will just try now to find the other place where water is getting in.

Excellent product for sealing/bonding materials exposed to sunlight
This caulk arrived quickly and had a fair price. It makes an excellent watertight seal on exterior materials exposed to the sun and weather.
