Thinning PRC
I've got a large quantity of out-of-date PRC to use on a Museum restoration. Is there anything that can be used to thin it? I've tried boiling the Semkit for half an hour in a water filled saucepan but it wasn't a total success.
Any suggestions for a thinning agent? Cellulose thinners is about 75% Toluene.
Thanks
