Hi guys, I coated my 1m squared porch floor with 3kg of GlassCast 3 Clear Epoxy resin. Looks fantastic. One problem. It was curing for best part of 5hrs when I noticed a small bug lying on top (slightly under). Annoying as this is, can I wait till the resin has cured fully then sand down the top? If so what type of sandpaper would do the job? I assume a wetsand grit of about 600+ would do it? Will the shine be harmed by this?
