I hope it wasn't glazier's silicon??
Any of the neutral cure silicons will do the job timddo has described and sikaflex works real well.
Glaziers silicon is acid based and will destroy wires fairly quickly.
Timddo...if you want some small stranded tinned wire (old PABX hook up wire) I have oooodles of the stuff that I'll donate to worthy causes such as yourself...all different colours too
