Aquatech Marine Canvas Waterproofing Spray restores water repellency to aging boat canvas, covers, biminis, and enclosures. A single application seals leaky seams, stops drips, and keeps fabric breathable and clean — without the oily residue or dirt-attraction of silicone-based waterproofers. Treated canvas stays protected for up to 12 months in real marine conditions.
