Why UV Protection Is Crucial for Boats
Over time, UV rays oxidize your boat’s gel coat — turning it chalky, faded, and rough to the touch. This isn’t just a cosmetic issue. Oxidation breaks down the protective layer, making the surface more porous and susceptible to water intrusion, stains, and further fading.
Here’s what prolonged UV exposure can cause:
- → Faded and dull finish
- → Chalky oxidation buildup
- → Cracking or flaking clear coat
- → Reduced resale value and protection
Step 1: Wash Away Salt and Contaminants
Salt residue accelerates UV damage by holding moisture and minerals against the surface. Start by rinsing your boat thoroughly and washing it with The Super Soaper. It’s marine-safe and powerful enough to remove oxidation residue, salt, and grime without stripping existing protection.
Use a foam cannon or pump sprayer for even coverage and rinse thoroughly before moving to polishing or protection steps.
Step 2: Polish Away Oxidation
If your gel coat already looks faded or chalky, you’ll need to polish before sealing. Use Picture Perfect Polish with a dual-action polisher or foam pad to restore clarity and smoothness. This step removes oxidation and helps your protection layer bond better.
Work small sections at a time and wipe away residue with a microfiber towel. The result should be a deep, glossy finish — ready for ceramic protection.
Step 3: Apply UV-Resistant Ceramic Protection
Once the surface is clean and polished, seal it with Tough As Shell Ceramic Spray. This product is engineered to block harmful UV rays while adding a slick, hydrophobic coating that repels salt, grime, and water spots.
Spray a light mist onto the surface, spread evenly with a microfiber towel, and buff dry. The UV inhibitors in the formula prevent oxidation and fading — keeping your boat looking new for months.

After sealing, regular maintenance ensures your protection layer stays strong. Rinse your boat after every outing and use The Super Soaper weekly to wash away salt and contaminants. Avoid harsh degreasers or dish soaps, as they can degrade your coating over time.
Reapply Tough As Shell every 4–6 weeks or after heavy use for maximum durability.

Pro Tips for Maximum UV Defense
- → Store your boat under cover or use a UV-resistant cover when docked.
