10 Best Convertible Top Waterproofing 2025 in the United States

This fabric waterproof spray from Better Boat is designed to protect and restore water repellency on convertible tops, boat covers, outdoor cushions, and similar materials. One of its strongest points is how well it causes water to bead up and roll off fabrics and vinyl, which is exactly what you want in a waterproofing product. It’s water-based and silicone-free, making it gentler on materials compared to harsher solvent-based sprays. This also means it creates a breathable barrier, so it won’t trap moisture inside the fabric, which helps prevent mold and mildew.

The spray comes in a large 1-gallon container, which is convenient if you have a lot to treat, like boat tops or multiple outdoor items. Application is straightforward: just spray on and let it dry. The spray is compatible with a wide range of fabrics including marine canvas, vinyl seats, tents, and clothing, making it versatile. It’s unscented and low odor, which is a plus for outdoor use.

It is a practical choice for maintaining water resistance on convertible tops and outdoor fabric items, especially if you want a gentle, easy-to-use option.
