I guess I need to apologize for my comment BUT I have been through soooo many surfacers, until I started using whisper wash products I was replacing rotary unions every 3 to 4 months , but ours get a lot of use. We have had some of our Big Guys for over 2+ years and just now had to rebuild the first rotary union (swivel)
O.K. got on the phone and found this one, New with warranty, guy said they bought it at an expo. Paid $399.00 not a typo $399.00 my machine may be a little small for it but it is still a HECKUVA LOT FASTER THAN A WAND.
