Restore Fiberglass Boat Hull Without Wet Sanding
Check out this video that demonstrates a fiberglass restoration product from Biokleen marine cleaners on the exterior fiberglass of a boat hull. They use two different steps in the video, a fiberglass restoration compound extra cut and a final compound to restore and polish the gel coat. You can see even after the first application the dullness and oxidation on the fiberglass boat is gone and you can see a huge difference on the shine. Then after the second application it add a nice high gloss shine, adding protection and sealing the surface.
We’ve seen a number of demonstration videos that claim you have to first wet sand the fiberglass surface (sometimes with 2-3 different applications using a finer grade grit each time), then follow up with a heavy compound, sometimes another compound, and then, finally, buff the fiberglass boat hull with a marine polish. Whew! It’s a lot of work, which is why the professionals at marinas and marine detailing businesses charge big bucks to restore the fiberglass on someones boat hull. Granted, if you have some deep scratches in your fiberglass, you’ll need to wet sand those areas first; but with using this process it seems to take out most of those steps.
You can hear the guy in the video on the orbital mention that he’s not using a lot of pressure and it’s getting the job done. He says “with the 3M compound I’d feel like I just got done with a 20 minute workout after 5 minutes of buffing.” This application with the Bio-Kleen Restore & Shine seems to go pretty quickly and seems easy enough to restore your own fiberglass at home, without taking it to a professional buffing place and shelling out a lot of cash.
