No, I've only tried beadlocks once, and that was to prevent air loss when 'wheeling. Found that it's usually the inner bead that lets go first anyway, so I pursued other ways to be able to run at between 1 and 5 psi.
Regardless, it doesn't make soapy water good for mounting tires. Better than WD-40 obviously, but far from good. Again, there are products made for the purpose.
