This generous 3 oz. bar can be used on canvas and cotton jackets, tents, bags, packs, shoes and more. Also works on materials such as poly/cotton shop jackets. The combination of natural waxes and oils found in their Cotton Canvas Wax works to not only keep wind and water out, but also adds a unique and notable finish to any fabric. Simply warm up wax puck with a hairdryer to soften, then rub on fabric, like a crayon, saturating entire surface to be waxed. Then use hairdryer again on waxed fabric to melt in.
