Best on the market

Seams a good product, worked with a polishing wheel

Brilliant product for my partner’s boat

Easy to use surprisingly does defy logic and works.

Worked very well great for removing oxidation from top coat

Eine der besten Polituren für Boote die ich je hatte. Richtig gut wurde das Finish aber erst nach dem Wachsen vom gleichen Hersteller!

We use the 3M Gelcoat Medium Cutting Compound in our fiberglass pool manufacturing, and it consistently delivers excellent results. It’s highly efficient for polishing gelcoat surfaces, fine scratches, and dullness with minimal effort. This compound lives up to its description—easy to apply, spreads evenly, and buffs out smoothly to a clean, high-gloss finish. It saves us time and labor while still achieving the professional look our customers expect. We’ve tried other products in the past, but 3M’s formula is reliable and consistent, making it our go-to choice in the shop. Whether it's final detailing or restoring shine after surface prep, this product performs exactly as it should. Highly recommended for anyone working with gelcoat surfaces who needs professional-level polishing and lasting shine.

This worked perfectly. I had squirrel marks on a black truck from car washes and this took the squirrel marks out and put a glaze finish on my paint.

Super Politur. Haben wir für Boot gekauft

Great 3M product. I used this product on a Ski Nautique boat fiberglass gel coat that had hard water mineral spots that were very visible on a black stripe and also a red stripe along the sides of the boat from the stern to the bow. I used a variable speed electric rotary buffer at lower speeds and applied the 3M Medium Cutting Compound and buffed it until the material was pretty much worked in. I was able to remove all of the hard water mineral spots so that the gel coat is now smooth any shiny. I buffed the boat in cooler temperatures in the low 60’s so that I had plenty of working time. Absolutely the best cutting and polishing compound that I have ever used at a very reasonable price point.
