Application: Gelcoat Finishing, Refining Scratches. 3M’s fastest-cutting gelcoat formula for removing heavy oxidation and P800 scratches. Suitable for all gelcoat surfaces including marine, RV and industrial.
Used this on my 2000 Rinker. The pervious owner bottom painted the boat so I had to sand off the bottom paint and I used the 3M 36103 Perfect-It Gelcoat Heavy Cutting Compound to bring back the shine! It worked great at getting out the 600 grit sand paper lines and left a beautiful shine. The entire outside of the boat was also looking worn and faded. After a good buffing it brought back the showroom shine!! Love it! I plan on doing the exterior again next year but moving up to the 3M Perfect-It Gelcoat Light Cutting Compound to get an even higher gloss. Great stuff!! Easy to work with and great results!!
