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.

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.

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.

I am amazed how great this turned out. My motorhome is originally tan however, overtime it has become gray and dull. After alot of hardwork, I was pleased. The motorhome looks just like when i bought it.. Long term I am not sure. It rained 24 hours after i finished and there were water lines all down the sides. After drying i had to redo the areas. Im living in the moment until the next rainfall.

Quick delivery, product works as illustrated. Works well on restoring the gel coat finish on my boat. Also used it, on my motorcoach. Fairly easy application, took off the oxidation and added a nice clear shine. Great value for the money.Time will tell how durable it is. Another grade 3 product. Would buy from this dealer again.

3M products are the go-to in my opinion if you want a good quality product to use to polish whatever it is you need to give a good shine to. It did it's job polishing the boat and bringing back the shine and cutting through the oxidation. Good value for the money also

This product worked well on my fiberglass/gel coat camper with mild oxidation. Easy to use with power polishing tool. Shined to glossy finish very quickly.

This stuff gets the job done and quick! My boat fiberglass hull was pretty oxidized. I scrubbed it down with a grey scotch bright pad to get the chalk layer knocked down, then went right to this compound after it dried. Instantly I have a mirror finish on the hull. I used 7" wool pad on my rotory on its lowest setting and it shines up in no time.

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

Best on the market

Super Politur. Haben wir für Boot gekauft

Seams a good product, worked with a polishing wheel

Das beste Produkt was ich bisher hatte lässt sich gut einarbeiten ( Poliermaschine ) und der Lack sieht aus wie Neu !
