Jim, I also have one of those bubble balancers. But often I just take them to a local shop that spin-balances for around $3-4 each. Mainly because I don't keep the weights on hand. Seems you need different types of weights for various types of wheels. And I've had a couple issues with them staying on, but that is likely operator error.
Ya, some great online videos of guys blowing up their wheel/tire/hand/face using various combustibles to seat the bead. I've never tried one, but those 'air bazookas' seem to work well. Again, a good lube helps a lot. I've used a ratchet strap around the perimeter of the tire to help squeeze the beads outward while seating difficult ones. Also remove the valve core and crank up your compressor as high as it will go, and hold on.
Janis, those are the tire irons that I mentioned will give you a really cool "tattoo" looking scar on your forehead when it slips off the bead.
Back on the subject of lubes. Because I'm currently living in a climate with 0 humidity, off the chart UV levels, and excessive heat, things tend to evaporate and dry-out REALLY fast. Even normal tire mounting lubes will get too dry to work by the time you get things going (I know, an extreme situation...it turns powder coat finishes to chalky dust). So I found one that is more of a thick cream, almost the consistency of petroleum jelly, but also kind of waxy. It does not dry out so quickly and helps for my conditions. It came free with the "No Mar" lever-bar I posted about earlier. I like it, but the stuff you show will work great in most environments. [If my shop wasn't so crowded with other equipment, so I could use the tire changer inside instead of out in the sun it would also help. That's another reason I don't use the 'bubble balancer', just to exhausted and hot by the time the tires are mounted.]
