Canvas Revive water-based acrylic coating. This is the actual coating that the RipTech Rip-Stop canvas is treated with during manufacture that makes it waterproof. Paint it over any stitch seams or where-ever the canvas is showing some wear and tear to restore the waterproofing. Available in 1L or 5L and in clear as well as pigmented to match most of the RipTech colour pallette.
