you have a good point vagabond.....i used the compressor and sealant on a tire on my crossfire back in '04 and what a friggin mess it made.....i dont know if the charger one is the same, but with the crossfire, you had to hook the sealant to the compressor and it dumped the whole can of sealer in the tire.....i was in the tire shop when they broke the bead to patch the tire and when about a half gallon of white crap dumped out all over the floor of the tire shop i thought they were gonna throw me out....they looked at me like i was a complete moron and said "what did you empty 5 cans of fix-a-flat in there?".... we are probably better off without it anyways.....
