The Karma's did seal up fine with Stan's, and the one I have redone with Hutchinson's just as well.
As you know, the reason for switching to Protect'Air is the 2 year useful life and the fact that it is doesn't corrode rims or attack butyl in tires as Stan's might.

Actually, the Karma sidewall is less porous than the RaceSport version of the X-King.

The other thing I learned, but is no big deal, is that the propellant in PitStop (and Fast'Air, I think) is propane and will leak out of the tire faster than air.  So they will inflate the tire just fine, but it will be low on pressure the next morning.  Reminds me of when CostCo used Nitrogen for airing up the tires they sold.  A larger molecule less affected by temperature, nitrogen filled tires will hold consistent pressure for a year.

As far as a lab mouse, I think Epic has already done much of the "lab mouse" work for both of us.
