Yeah that is the method we used to do in the dirt car.

I found another little trick is to seat the bead with starter fluid first than immediatly hit it with the air. When you air the tire up put it at around 30 PSI. The started fluid really gets the sealent to bond when it heats up and than at 30 PSI the bead has alot of pressure against it and really gets a good strong seal. i usually leave the tire at that pressure for atleast 24hours just to be sure.

If you dont know how to seat the bead with starter fluid either dont do it or be VERY VERY careful.

At schwabs we either use the truck press or dont touch them. At home i have always double hooped, two seperate hoops, a tow strap and than chained the wheel to the bottom of the corner fence post, 2'x2.5' block of concrete, and tied the strap to the chevy and start pulling. I had to put the chevy in 4wd to keep traction on dry asphalt...
