Chemical Guys Heavy Metal Polish for Chrome, Aluminum & Stainless — 16 oz, Restores Shine & Protects

Chemical Guys Heavy Metal Polish Restorer and Protectant is a concentrated metal polish that cleans, removes oxidation and stains, and leaves a protective, high-gloss finish on chrome, aluminum, stainless steel and other metals.

Whether you’re refreshing wheels, bumpers, exhaust tips, fixtures, or marine hardware, this 16 oz formula tackles tarnish, rust stains and light corrosion, then deposits a protective seal to slow re-oxidation. Designed for both hand and machine application, it’s formulated to cut through built-up grime and restore a mirror-like reflectivity without harsh abrasion when used as directed.

How well does it remove oxidation and rust stains?

Heavy Metal contains active polishing agents that lift oxidation and surface rust without aggressive abrasion when applied correctly. It works on light to moderate staining and is ideal for restoring visible shine to weathered surfaces.

• Breaks down oxidation and surface rust on chrome, aluminum and stainless.
• Removes tarnish and light discoloration from copper, brass and silver.
• Suitable for moderate buildup; heavy pitting may need mechanical repair first.

Can I use it on automotive and marine parts safely?

Yes — the formula is built for automotive, motorcycle and marine metal components. It restores trim, wheels, exhaust tips and railings while providing a short-term protective barrier against the elements when properly applied and maintained.

• Safe on chrome bumpers, stainless railings and polished aluminum surfaces.
• Effective on boat hardware and marine stainless when rinsed and buffed dry.
• Not a replacement for structural corrosion repair on heavily corroded components.

How do I apply it for best results — by hand or machine?

Apply sparingly with a microfiber or foam applicator for hand polishing, or use a dual-action polisher with a soft pad for faster results on larger areas. Work the polish into the metal until defects diminish, then buff to a high shine; repeat if deeper oxidation remains.

• Hand: small amount on a microfiber or foam applicator, rub in circular motions, buff with clean microfiber.
• Machine: low-to-medium speed, soft polishing pad, wipe residue and finish with a clean towel.
• Finish by rinsing marine parts and drying thoroughly to prevent water spots.

How long does the protective seal last and how often should I reapply?

The polish lays down a protective layer that helps resist immediate re-oxidation and grime, but longevity depends on exposure. For vehicles and boats exposed to weather and road salts, reapplication every few weeks to months keeps metals looking their best.

• Light exposure: reapply every 2–3 months for optimal protection.
• Harsh environments: check and reapply monthly or after cleaning with harsh cleaners.
• Regular light maintenance extends time between full treatments.
