Boeing’s use of Prolong Ultra Cut for machining applications has had positive results. Prior to addition of Prolong’s Ultra Cut 1, they could not get one 10″ deep hole completed with a drill lasting the entire hole. Using Prolong, they could complete six holes per drill- Applied by misting, not flooding. Further, metal-cutting saw blade would squeal and make all kinds of racket and chatter. With Prolong they now have a very quiet result.
