Roymail, I filled the outsides with epoxy resin, drys super fast, there was not much to file, but the 1 inch mdf took it well. i over filled it and let it dry. When done, i had to RE router the edges to get the same look, sand smooth, prime and then had my friend re spray them in the black. There is no money it anymore, just trying to get back the money on the sheets of no rez, mdf sheets and let someone have a crack at them. I figure the buyer will enjoy them even if they knew they were dropped, thus the price...180 minus 50 for no rez, and 45 for shipping... 45 bucks for 1 inch mdf, not much left, oh, and i think there are two sheets of no rez in there.. maybe 1.5 or so. Hope that helps... bought the epoxy at Home Depot.....It routered out well too...
