About 2/3 the DIY’ers using Epoxy love the high shine they get from their final flood coat. The rest prefer sanding and polishing their epoxy. This process does take some practice to achieve your expected results . We recommend practicing on a sample board to achieve your preferred sheen level. These sanding discs can also be used for removing small imperfections, including scratches that may be in final flood coat. You’ll start with the lower grits 220 and work your way up to the higher less abrasive grits before you start to polishing.
