1. 303 Marine and Recreation Aerospace Protectant
Okay, think of this as sunscreen, but for your boat gear. I use it religiously on vinyl, rubber, and plastic surfaces. The first time I used it on my seats, I was skeptical—could this make a difference? But the results were instant. My dull, faded seats looked alive again, with this smooth matte finish that wasn’t even a little bit greasy. What sold me, though, was the UV protection. I had a problem with my seats fading every season, but not anymore. And when the water beads off the surface after a rainstorm, it’s such a satisfying sight! It’s become my go-to for keeping my boat looking fresh under the sun.

Once, I forgot to clean the salt off, and boy, did I regret it when the corrosion showed up! After using this product, my boat not only stays clean, but I also feel like I’m preserving its lifespan.

It made my dirty hull gleam like a mirror again. The best part is how far it goes—just a small amount creates rich, foamy suds that cover a large area.
