REVIEWS

Used this to seal a dodgy leak in the boat canopy and it's held tight through wind, rain, and a fishing trip. Set quickly, easy to apply, and looks clean.

This sealant is excellent. Used it on my ute canopy and a leaky window at home. Cured fast, waterproof, and still holding strong weeks later. Highly recommended.
