This question reminds me of a time when I used Slime in my vehicle tire. As I went to a tire place to have new ones installed, they asked me 50 questions about my vehicle...after they pulled into the garage to change the tires, the service manager came out and scolded me for having slime in the tire and not telling them (must have made a mess)...after getting pi$$ed of I asked him why they didn't ASK people that to begin with...he sort of stammered and said that wasn't their policy....point is I guess those garage people don't like it?-LOL
