I started using this on the sides of my hot tub after the sun began fading and dulling the original finish. The constant sun exposure was really taking a toll, and this did a great job bringing the look back while adding protection. I recently tried 303 Products Marine Clear Protect, and I’m genuinely impressed. It does exactly what it claims—creates a protective barrier that helps prevent fading, chalking, and oxidation. I used it on my boat’s gelcoat and upholstery, and everything looks noticeably cleaner with a deeper, richer finish. Application couldn’t be easier—just spray it on and wipe it off. No greasy feel, no streaks, and it dries quickly. I also tested it on my car’s trim and tires, and it restored a clean, like-new appearance that’s held up well against sun and rain. If you’re looking for a versatile protectant that actually works and helps keep surfaces looking great despite harsh conditions, this is a solid choice. Definitely recommend.

This stuff is great!! I used it on my boat windows and on my Argo windows. It seems to soften the vinyl and when you look at the windows after, you think they are brand new. Definitely clean the windows before with water and remove them from the vehicle first. You will be surprised how great the windows will look after!
