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.

Great cleaner and protectant—I used it on outdoor gear and it really restores and shields surfaces. Works just as well as the premium brands, but at a nice price point. Quality is dependable and I’ll keep buying this one.
