60 grit is a bit aggressive for this. I use 100, but 80 would be OK with care. Does the sanded area go dark when you wet it with water or alchohol? That would be proof positive of bare wood. Also the ability to dent it with your thumbnail. If not, the light coloration could be the matt finish that the 60 grit produced.
