Absolutely. A number of System Three products can be buffed and polished once fully cured. This process will remove dust, surface scratches, and other minor defects. The video below details how to buff and polish our popular MirrorCoat™ bartop coating. The same process can be applied to buffing and polishing Pennant Paint, Marine Spar Varnish, and our other epoxy coatings.
The same process is used to increase or decrease gloss, depending on the grit of the abrasive being used. See the MirrorCoat Buffing & Polishing Procedure below for detailed instructions. To achieve a lower surface gloss, use the reverse of the steps shown in the video, and skipping the polishing step.
Note that when reducing the gloss through sanding, the scratch and mar resistance of the coating is greatly diminished.
System Three® also offers a sanding and buffing kit
