This forms a sealing gasket like some of the much more expensive stuff
I used this product to seal acrylic windows to a fiberglass sailboat's cabin sides. I learned the hard way that the cabin side was curved, not flat. This product created an adhesive seal for those acrylic port lites on the cabin and was basically fully cured in 24hrs. I'll be stunned if they pop off or leak again, as they were. My only comment is that it is hard to get a clean finished edge. Unlike silicone sealants, where you run your finger along and get a very smooth finish, this was harder to work for that finished edge. I used paint thinner on blue towel and tried to get a good edge, but it looked a tad rough. Not shiny smooth. If that's my only problem, this product is a winner.

Worked for me
Got this to repair/rebuild my old work boots. So far it's worked great. Filled cavities in the soles and reglued the soles to the uppers. I wear the boots daily and they're holding up great after a couple of months already. Recommended

Works Great
I used tape to secure superstrut to my cargo roof for solar panels. The roof wasn't completely level and I used this to fill gaps. Easy to use and messy. You will not be able to smooth bead this like silicone. Impressed with product.

The Real Thing
Sealed my Old Artic cooler. Looks ok, but worked! Hard to feed with caulk gun. Have your project ready to go- sets quickly.

Just what I wanted
Car got wrecked, needed something to “glue” the front clip back together and this was perfect. Dried quick and strong but still flexible and no shrinkage. If it stands up to time and weather it’ll be perfect
