How to Protect Aluminum and Metal Trim on Boats

Why Metal Trim Needs Extra Protection
Metal trim, rails, cleats, and outboard parts take the most abuse from salt, UV light, and oxidation. Over time, that exposure leads to pitting, surface rust, and dullness — especially in marine environments like Florida’s saltwater coastlines.
Proper care not only keeps your metals shiny but also prevents corrosion that can compromise structure and performance.
Common Metal Types on Boats
Knowing what type of metal you’re working with is key to choosing the right products:
- → Aluminum: Lightweight and corrosion-resistant but prone to oxidation and dullness.
- → Stainless Steel: Durable and shiny, but still vulnerable to pitting if not protected.
- → Chrome: Offers high gloss but easily spots and stains from salt.
Step 1: Rinse and Pre-Clean
Start by rinsing your metal surfaces with freshwater to remove salt and grime. For a deeper clean, pre-soak using The Super Soaper. It breaks down grime and salt without damaging coatings or finishes.
Spray or foam it on, let it dwell for 2–3 minutes, then rinse thoroughly. Dry immediately with a Massive Drying Towel to prevent spotting.
Step 2: Polish the Metal
If your trim or aluminum shows oxidation, polish it using Picture Perfect Polish. Its micro-abrasive formula removes oxidation, water spots, and haze while restoring depth and clarity.
Apply with a foam or microfiber applicator and work in small sections. For tougher oxidation, use a polishing pad with a DA machine. Wipe clean with a soft microfiber towel.

Once polished, seal your metal with Tough As Shell Ceramic Spray. It forms a durable, hydrophobic barrier that prevents future oxidation and water spotting.
Simply spray onto the metal, spread evenly with a microfiber towel, and buff dry. It works on aluminum, stainless steel, chrome, and painted metals.
Step 4: Maintain Regularly
After each use, rinse your boat and metal surfaces with freshwater to remove salt. Wipe dry and touch up with Tough As Shell every few weeks for continuous protection and shine.
