Meguiar's M67 One Step Marine/RV Compound 1 gal — Cuts Oxidation & Restores Gel Coat Gloss

Meguiar's M67 Marine/RV One Step Compound is a single-step cutting compound and polish designed to remove oxidation, scratches, stains and tough water spots while restoring gloss to fiberglass and gel coat surfaces.

If your boat, yacht or RV surface looks dull, chalky or marred by water spotting, this Meguiar's one-step product combines cleaning, cutting and polishing into one application so you can recover color and shine faster. Formulated for gel coat and fiberglass, it works by lifting contaminants and abrading just enough clear layer to reveal a smoother, glossier finish without requiring a separate polish.

How quickly will this compound remove oxidation and scratches?

Meguiar's M67 is formulated to be aggressive enough to address moderate to heavy oxidation and light-to-moderate surface scratches in one pass, yet controlled so it can be used safely on gel coat. Results depend on severity: deeper gouges may need additional sanding or repair before compounding.

• Removes heavy oxidation and embedded stains from fiberglass gel coat
• Reduces visible light scratches and scuffs in a single-step process
• Works effectively by hand or with a variable-speed polisher

Can I use this product by hand, or is a machine required?

You can use M67 equally well by hand or with a machine; the formula is engineered to deliver visible cut and gloss in either method. Hand application gives more control for small areas, while a dual-action or rotary polisher speeds coverage on large hulls and RV panels.

• Hand-apply with foam or microfiber pads for spot corrections
• Machine-apply for faster, uniform results on broad surfaces
• Compatible with common cutting and polishing pads to optimize finish

Will this compound affect the color or finish of my boat or RV?

The compound is designed to restore original color depth and leave a high-gloss appearance, improving the look of faded gel coat without altering pigments. It removes surface contaminants and oxidation that often make colors look dulled, returning a richer, brighter finish.

• Restores color vibrancy and depth to neglected gel coat
• Delivers a glossy, lustrous finish after compounding
• Safe on marine and RV gel coat when used as directed

What preparation and aftercare does the product require?

For best results, start with a clean, dry surface free of loose debris and heavy contaminants. After compounding, inspect for remaining flaws; follow with a finish polish or protectant if longer-term gloss and protection are desired.

• Wash surface and remove salt, grime, and loose oxidation before use
• Apply with moderate pressure; wipe away residue and evaluate results
• Consider following with a polymer or wax sealer to maintain gloss

Who is this for? Meguiar's M67 Marine/RV One Step Compound is aimed at boat owners, RV enthusiasts, detailers and maintenance professionals who want to recover neglected fiberglass and gel coat surfaces efficiently. If you need a versatile compound that cleans, cuts and polishes in one step—usable by hand or machine—M67 is formulated to restore color and leave a high-gloss finish on marine and recreational vehicle exteriors.
