Excellent Sealant for Multiple Uses

This product is a great product for sealing leaks, bonding materials, or weatherproofing. I used it on a cracked window frame, and it held up perfectly against rain and wind. The clarity is excellent, and it doesn’t shrink after drying. Works on glass, metal, and plastic very handy to have around

More useful than the readily available sealants

Full strength RTV silicone selant/adhesive with no fillers and a sharp whiff of vinegar. More useful than the readily available sealants.

The silicon inside tube was not accessible easily

It was very tough to use it. Had to press very hard for the silicon paste to come out of the tube

Does not work

Did not stick to metal or plastic or silicone surface. A thick layer of application can be just shaved of by picking by fingernails.
