Query: Junk

I got this stuff at Wal-mart thinking it would prevent flats, but instead it caused a flat. I followed the instructions just like it said and the first ride I went out on it was flat by the time I got back. I looked at my tire and found the hole. All the slime did was ooze out like snot. I thought maybe it just needs to dry to seal it but even after a few days it is still slimy and no good. Now I have to by a whole new tire and throw out the one with the slime I just put in it. This stuff sucks. I posted a picture.
