So I have a set of wheels set up with UST tires and Stans sealant inside. A buddy of mine did it for me about 3 weeks ago. I am going to take the tires off. I just dont like the UST selection. (I realized that I am addicted to Kenda Stick-E's) Anyway, is that Stans goop gonna spill out all over the place when I take off the tires? Any precautionary measures that I should take?
