Solutions;
- Reduce horsepower.
- Use less brakes.
- Make car lighter
...
- ROUGH UP wheel lips, like 40 grit on a D/A rough.
- Clean tire bead with lacquer thinner. Remember the same release agent that you
heat cycle out of a tire is there too.
- Use NO soaps or sealers.
- Air up to 40PSI and leave that way for as long as you can.

You might want to read the directions on the contact cement and think a bit. The reason the hair spray works is it is slippery and works as a lube during install but turns grippy after some time. The contact cement works by being brushed onto both to be mated surfaces and the solvent evaporated prior to being mated together. It bonds by grabbing to itself when the two treated surfaces make contact. How you going to mount the tires?
You mentioned that the tires were flipped. Did they rotate on the rims before they were flipped?

Yes they rotated prior to being flipped but I never asked Paul to use the hairspray because I didn't know about it back then.
Kurt, do you know if the X-tra Seal is available locally?

Larry, Yes I understand you know how contact cement works but you might not be as spun up on peformance tire mounting. They don't just slide gently onto the rim and are a far harder task if you were to try it dry. Bead damage while dry mounting is not unheard of. Keep it simple. Use the existing method right and it works.
Hair spray on a dirty rim and greasy tire is not the corect method. the tires and rims have to be clean. Offer to do the cleaning of rims and beads after they dismount the old tires.

The Hoosier R6's that I use, mounted on CCW rims, always rotate substantially. Not much noticable vibration until day 2, then the wheels and tires feel somewhat "square" for a few laps, then they are ok for the rest of the day. I asked around about the hairspray solution among some hardcore professional racers - they laughed. So I don't worry about it anymore.
