I just found a new way of using acetone. I managed to slop some thick super glue on a resin model (it oozed out where two parts bonded. Rather than trying to sand, I wrapped the part in a paper towel and drizzled acetone (fingernail polish remover) on the towel, keeping it moist but not dripping wet. In a half-hour, the super glue had melted away. Saved me a lot of work, with no muss or fuss.
I also use acetone to remove excess putty. I get Bondo glazing putty at an auto store for a fraction the cost of “hobby putty” and when I need to, I use it like putty. But instead of sanding, I lightly dampen a paper towel with acetone (not anywhere near as much as for super glue) and wipe it off. Fantastic! It remains in scratches and gaps but disappears where you don’t want it.
My wife’s not happy to lose her nail polish remover, but my models are ecstatic to not be sanded!
