I started a EM topic about Butchers Bowling Alley wax . I started using Butchers in 2011 when I bought my first machine and have been using it twice a year on 4 machines ever since. It's hard to rub off but does a great job. It was given to me by Russ Snyder of Pinrescue and I'm sure he knows what he is doing. I didn't find one person who uses it. Acouple have tried it. I'm talking about EM playfields I'm an EM guy it's all I have
