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.

GOOD STUFF FOR BOAT WORK, AND IT HOLDS UP!
09/14/2016: I still swear by this product. Just had two more tubes delivered. This is a good product. It remains pliable and holds strong to porous surfaces (wood, brick, cement, hands, fingers, hair etc). Give it 48 hours to cure before stressing, flexing or painting over it and it'll make a good/successful bond/seal. I use it in boat building and repair and for about half the cost of the similar 3M products, this is a good deal. It also makes a good window sealer, especially for boats due to the pliability. Boats flex and a sealer that is too stiff will start leaking within 1-2 years. It does shrink a little so keep that in mind if using it as a decorative trim. Try it, I think you gonna like it. Keep it off your hands. Now to test a tube of the white. Thanks AU //(~_~)\\

Dap roof sealant
The product seem to work but it must’ve been damaged a little sense it leaked out of the bottom of the container.
