I tried a different brand last time I was in walmart they have some stuff that looks like slime but is yellow. I believe it was prestone but dont hold me to that. It was about a third cheaper than slime. I bought a gallon of it and it seems to have worked everywhere slime did and maybe a couple of places slime did not work before. I bought the gallon jug of it and have put it in tires with tubes and without. I have a hand truck that has tubed tires on it. I put slime in there before and they went down. I put the yellow stuff in the tubes about a month ago and just spun the tires by hand. So far they tubed tires on the hand truck have not went down.
