Good grip, but give it time to dry.
Used this on an unusual application on nylon felt. Good grip strength. Bonds to glass really well too - by accident. It would be nice to have this come with a wire to rupture the membrane at the base of the nozzle - or a shorter nozzle - it is too long for any commonly available nail to reach.

Smoothes easily - a joy to use.
My application was to seal the edges of my much-used Toro Timecutter SS 4235 lawn tractor seat where the vinyl is supposed to meet the HDPE shell. The sealant tube manufacturing date is located inside the tube on the cap that is pushed by the caulk gun. My tube was manufactured 11 months before shipping to me. The consistency of the sealant was similar to cake frosting from a store-bought can. A wooden craft stick easily smoothed the sealant where I wanted it to go. The finished result looks much better than I expected. After first using paracord to mechanically stitch the vinyl through a few holes I drilled in the HDPE seat shell, I used most of one tube on the gap at the seat edges and it seems a very sturdy repair. The sealant covered the gap and the paracord knots. I used the leftover sealant on the lawn mower tires where blocks of tread had broken off. I don't expect the tire repair to last, but it cannot hurt to use the sealant there and I don't want to try to store an opened tube of sealant for very long. Even though the sealed gap on the seat looks just fine, I did purchase "CRAFTSMAN Riding Mower Seat Cover, Large" which fits the seat exceptionally well and hides the repair completely. I will look for more applications for this sealant and will gladly purchase it again.
