Time consuming to apply adequately.
Fair price. Not as thick as a different product. Took 3 coat’s of base and 3 coat’s of finish product to adequately cover RV rubber roof. Does appear to work. Time consuming over multiple day’s to apply.

Don’t waste your money on any Kst products
I bought 7 5gallons buckets of kool seal. Trying to seal a roof leak on metal. After 3 tries, I completely give up on the product. I followed the instructions, applied on the dry surface at high temperature range over 80. After two weeks of sunshine, first storm comes, the roof leaks, I climbed on the roof, the material is completely like jelly. Don’t waste your money on this product
