I have a mould that has been coated with S120 to leave a nice glossy finish. Thanks to another problem I now have lots of raw infusion resin on the mould surface. Can I clean this off with acetone or easy composites mould cleaner without damaging the S120 surface coating? If not, is there anything I can clean the in2 resin off with and leave the S120 surface intact? Any experiences gratefully received, thanks.
