The Prolong Water Soluble Ultra Cut 1 Cutting Fluid, when compared to our best water soluble oil, has proven to last over five times longer. This product has also extended tool life over 30% and significantly reduced operator adjustments normally required for compensation of tool wear. This product has also offered exceptional rust inhibiting protection of parts subject to a hot and humid environment. Product was applied to carbon steel test samples that had one side with a ground finish and then placed outside in the rain for five days, and then placed indoors for over one month.  The results have been excellent.  Each sample showed minimal signs of rusting after this test period. I hope that our favorable experience with your product will reinforce your continued success in the promotion of these remarkable products.
