James,

The dampers do form a water tight seal against the metal, provided that
they're
properly installed. Keep in mind that the majority of vehicles on the road
come with
  OEM dampers - although they're not installed throughout the vehicle.

Removal of the dampers is rare, but can be done if needed. It involves heat,
some
elbow grease, then a degreasing style product (even WD40) to remove the
residue.

Thank you for your interest in B-Quiet. If you have any further questions,
please let
us know.

So, supposedly it's water tight.  But, it doesn't sound like there's an
special/easy way to remove the stuff.
