many of us faced w/ a leaking head gasket (143,000 miles) have figured
there is not much to lose by putting bars leak in our coolant.
if it plugs up an engine w/ high miles, so what? it's on its way out
anyway.
rear heater, radiator, front heater---from list members reports, it
sounds like you don't need to add bars leak to encourage their demise.
my motor was leaking and dripping at the four corners. you could smell
it a block away.

1990 w/ 8,000 miles on bar's leak.
to date:
rear heater hot
front heater hot
radiator, no change(of course it's winter in wisconsin)
heads, no leaking

i used a small bottle of the stuff--not the s.u.v. size. it is
impossible to know if the gray mystery blob was bar's leak, robert, but
thank you for bringing it to my attention. i will check under my t-stat
because i want to keep my original motor going as long as possible. runs
great. always starts. plenty of power(can't understand why anyone would
get a vw and expect more speed and power).
i would not add anymore bar's leak.  i am accumulating the necessary
parts for the wbx  replacement.

So , a bad head job led to leaks which led to bar's leak and silicone.
The leaking flange was the early warning that went unrecognized. Rather
than
try to figure out why the head would get hot enough to melt plastic, the

owner/mechanic justr went"ho-hum" and lathered on the silcone.

He had to have seen it was melting. Ad so his beloved or cursed Vanagon
ended up in the junkyard for which I am grateful.

So if you have leaking heads you haven't told anyone about, and you've
put a
bunch a Bar's leak in, at least remove the thermostat cover and look
under
the thermostat for a gray blob.
