PHOF used Zeps for a long time. Good stuff but it's discontinued. They used to get it by the caselaod at home depot because it was dirty cheap. Any carb wax will do as long as it doesn't have cleaners in it.
I'd love to see a wax comparision on the same playfields. I only use collinite 885 now, but all carb waxes end up looking the same really. Only real noticeable different is smell. Some I can't stand, some are ok, some you can barely smell. Mothers is the worst imo. Stinks up the whole house. Novus 2 is just crap. Sorry nov fans but that stuff just sucks imo.
It's all like buying into snake oil.
