Well that would make a large pucker mark in the seat!!

I drive my Stag every year up and over the Continental Divide via Trail 
Ridge Road in Rocky Mountain Park - one of the highest continuously 
paved roads in the world at right around 12000 feet.

Last year the Stag was up Mt. Evans, the parking lot is over 12000 feet, 
and up to the top of Pikes Peak at 14,110 feet.  Never a problem.  But 
my fluid was installed at 5400 feet elevation, yours probably at sea level.

I wonder was caused the silicon to become entrained with air?
