I accidentally sanded my print a little too much, I don’t want to reprint it since it took 12 hours, is there something I can use like clay or putty that I can apply to readd the rounded art that is sandable and that I can put primer on and paint over?
You can put it on really thick, but it is probably better to do multiple thin coats. You can find it at auto parts.stores or some Walmarts in the automotive section.
