Keeps our boat looking good.
We apply this every year to the canvas cockpit enclosure of our boat. By sealing the fabric, we keep the cockpit dry, but also slow down the development of mold and stains on the canvas.

Does what it says on the tin
I’ve tried several brands of products for waterproofing. This one isn’t cheap but it works, though it smells very much like it contains the same stuff as Fabsil.
