Here's some parameters for fiberglass gel coat: This is the stuff for boats/RVs that are a few years old but don't leave a white dust on your shirt or hand if you brush it (after a good pressure wash, of course). If you're getting significant dust, you should probably dry-sand first, use this second, use a lighter compound third, then rinse or vacuum or blow off fourth and then wax. Compounding leaves significant abrasive dust behind on the boat that needs removed before waxing. The whole process takes several days to over a week for a 25-ft boat.. Sorry, but it does. I use this if wet-sanding is not quite necessary but somewhat close. It's a little more aggressive than Presta Gel Coat Compound, but not by much, making the Presto a very good second-rounder or for lighter work. (Presta also provides more shine at that stage but not as much efficiency at oxy-cutting.) 3M Heavy shines somewhat when done on glitter gel coat, but mostly provides a flat, polished consistency to the finished product when viewing askance to the light. It's unlike some with polish in them, which create a false impression that early in the process. 3M Heavy is indeed for cutting old oxy and must be used with a good rotary, not a DA. If you want oscillation, set your rotary's velcro pad off-center one or two millimeters. But muscle is required and consistent RPM rotary polishers provide this, along with the 3M Heavy. In hot weather, dot the surface being polished rather than applying it all to the rotary pad. Do a picking-up action as you rotate and as you keep moving. This keeps the compound from drying too fast upon use, because it's in a droplet and already placed, rather than smeared on thinly, as we're taught. This stuff is expensive, but when you're into working on something with a lot of value, it's best to spend the money and be sure you're making good progress safely. Never linger in one spot too long, as it can burn, but this is not likely if you keep moving and feel the surface frequently against your cheek. Review: Works Great - Low-Medium speed with heavy cut buffing pad with very light pressure went straight through oxidation GlideCoat wasn't having any impact on. In fairness, GlideCoat is a light-medium compound while this 3M product is a heavy compound. ## Features - USE WHAT THE PROS USE – Restore heavily oxidized gelcoat into smooth surfaces ready for polish so you can get back on the water or the road - SAFE FOR GELCOATS AND FIBERGLASS – Marine compound is scientifically formulated for boats and RVs - FAST-CUTTING FORMULA – Removes chalky residue and scratches ideal for compounding gelcoats - EASY TO USE – Apply using a rotary buffer with a white 3M wool compounding pad can also be applied by hand for small areas - PART OF A FAMILY OF BOAT CARE PRODUCTS – Choose 3M Perfect-It Medium Cutting Compound + Wax for removing moderate oxidation Light Cutting Polish + Wax for light polishing and Boat Wax for high-gloss shine - For industrial/occupational use only.
