No Leading complaints from my sales
I have sold thousands of the original Saeco Co. molds I designed to use tire weights for practice and adding a little solder for serious competition. I advised my customers to use standard diameter sizing dies in the Saeco and Star lubers I sold and use of the original Company Green lube. I have never had a leading complaint to this day. The original Saeco green lube contained expensive automotive STP.
I don't know what the current company uses.
