Review: $aved Big Buck$ - Seals almost anything. Just restored my split-seam $350 golf cart roof for just $42 total...
Review: works better than expect as put on with a brush - Works great and seems of good quality and can be layered to the thickness you want. As dries quick so buy extra brushes or rollers. Update 7-25 I needed this stuff to think out as using more like a paint where if you use it otherwise it kind of runs. Mineral spirits from rust oleum is what I used to thin it. Manufacture says you can't but you can and it still dries like normal as I first tested in a jar and solidified like a hard rubber surface. Just so you know nothing sticks to this stuff as paint and other type of rubber coatings unless it is of the same chemistry as why I had to thin this stuff out and use with a fine brush but dries fast like starts in minutes and then really unusable in about 15-20 minutes for the same effect.

### ⭐⭐⭐⭐ Works well, stores terrible
*by S***N on November 3, 2024*

Used to coat Texas-Sun exposed top edge of an Intex pool. Application went well and, so far, so good. Be prepared to throw away your brush and, please know, the product in the can will not stay a liquid, even with a can top perfectly installed and...sealed with flex seal. Buy only what you need
