Any oil /grease type of additive IMHO will inhibit the curing of Acraglass, if fact paste wax / any thick grease can be used as a release agent for Acraglas. To clean / dilute Ag acetone is a good solvent even if the Ag is cured. My only suggestion for adding colour to Ag go to some one like a boat builder etc. and get some dye from them. I think a trace of oil/grease kept the Ag from bonding to the horn - suggest a good soap & water wash as I don't know the affect of acetone on horn. --- John Can.
