I did have serious doubts (I knew that I was up s creek) about the effectiveness of the sealant when I saw the ragged puncture, especially after about a pint of the sealant squirted out of the tire. But, persistance paid off, at least enough to limp home. My choices were 1) work with the sealant until that method was exhausted 2) take the wheel off, take it to the tire shop, buy a new tire and have it mounted, return to car and put wheel back on (the car was in a questionable area of town and I didn''t want to leave it there on a jack and it was almost 6:00 pm, when most tire shops are closing) 3) Have the car towed home or to the shop. Needless to say, I chose to work and work with the sealant with hopes that we could limp out of there.

The tire was very slack, but not totally flat this morning (could probably still be driven slowly), still with a faint "sizzling" of air escaping. So the sealant did do it's job I guess. I found the key to making it work is driving the car slowly afterwards to spread the sealant around, adding air and driving more, etc. I do see how the sealant method would be easy to perform and work well with, say, a slow leak caused by a nail, etc. I just got lucky with the puncture.

I want the spare tire!!
