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.
