I have for sale about 5/8 of a gallon of this 303 Fabric Guard water proofing and preserving liquid. In the past I have used it on the canvas on my pop-up camper, my tents, and my boat cover. I no longer have any of these, so I no longer have any use for it.
It sells for $80 per gallon on Amazon. If you have any canvas that needs waterproofing , this is the product for you. Such as tents, boat covers, and much much more!!
