Has anybody tried both the Hater Sauce and Holy Water oils at different points for their Grand Prix cars and if so was there a noticeable difference between them? We have used Hater Sauce with DuPont for the last three years and have done pretty well, but wondering if it's worth the switch over. Another layer to add to this would using DuPont or Jig-a-loo with either of these oils and if there was any noticeable difference between those?
