Probably the best on the market. Super strong. Great elasticity. Takes a long time to set completely but when it does it lasts forever.

It does work as advertised but I don't see any better adhesion to it then the biggest seal that I get from my material vendor. I believe this can be used underwater so that would be a benefit but I was buying it because of the ability to stick to polyethylene better than most but I found that it still will peel with minimal effort.

Very good product, stick very well to gelcoat, metal and plastic.

This stuff has stood up to every project I've applied it to. Initially available only at the marine store (which is a substantial distance from my house), I'm delighted to find it here. I've used it to fill a large hole in the transom of my boat where some cables pass through, to attach fittings (without fasteners) and even patch a few tears in my trampoline mat. Not only does it adhere tenaciously, but it flexes and seems to be impervious to everything once cured, including UV. Note that it does take quite a long time to cure, however.

I used this to seal the joint between the coping tiles and the concrete deck around my pool. Getting water into the joint over time is a sure-fire way to loosen the coping tiles.It has resisted chlorinated water quite well and when dry the clear version is practically invisible. It skins over quickly but I was able to lay down a 4-foot length and tool it smooth before it began to resist being worked. Took some effort but I don't think I will have to do it again for a very long time.Good stuff and worth the price.

These were bad and useless could not use any of them ... I kept them in air condition so I know they were well taken care of at my end so they had to be old product when I received them...but I was not ready to use until I was getting ready to go camping so I have past the time for a refund
