I can tell you first hand these do not mix well. I was going to lunch today when an older gentleman ran a stop sign. I tested out my trucks ABS and my trailer brakes, they worked and I missed him by about 3 feet. I think my heart shut down for a second. While I was gathering my whits I noticed the car behind me had ran up on curb so I started to move and heard a hissing sound. I turned around and seen that the fluid film and the edger blades fell out of the back seat and into the floorboard, only problem was one of the cans had a hole in the side. Holy crap, by the time I could grab it and put it outside this stuff was everywhere. Well I guess the inside of my truck will not rust anytime soon. I love it when you throw 9 bucks out the window.
