I used it to seal my new OES tarp*, worked like a charm. It seems thinner than it is: so put it on thinner than you think it should be, it dries / sets up just about how you have it on the nylon. So, there are a few places on my tarp that had a few "glumps" on it, but the thick stuff peals off fairly easy, then reseal being careful next time. The thin spots stick like glue

Once I got smart, I used a sponge brush to spread the stuff thinner! So the glumps were on the first half of the ridgeline. 1 tube did a 13.5 foot ridgeline and a JRB stuff sack seams. Even with the excees I put on then had to redo.






*Brian sewed it in his dorm room, no ventilation or time for sealing.
