Gee, I dunno Paul.  I recall a once-very-secret incident when a certain
pioneering submarine (the Nautilus) developed a leak in their main
condenser.  Stopping in at San Francisco for a "liberty port", all the
swabbies were sent ashore with orders to fan out and buy all they radiator
stop leak they could lay hands on, but not to do it all in one place or to
raise suspicions.

Returning to the sub, they ran literally hundreds of gallons of the stuff
through the main seawater condenser (1 quart at a time), weighed anchor, and
proceeded to make the first submerged transit of the North Pole running
under the ice.  Pretty ballsy I'd say.  Can't glide to a force landing.

So Finn, have you tried Barr's Stop-Leak?  Wreaks havoc on old heater cores
by fouling the surfaces, but if you've got a relatively clean rad, it might
just work wonders.  Another mechanic's trick is to use a *small* amount of
ground black pepper.  It will find the leak and coagulate in it as it
absorbs coolant.  Warning:  I tried this with a leaking truck radiator and
put too much in.  Plugged the whole darned thing solid and boiled over in
~20 miles.

What a coincidence. We did that with Perry's broken tension bolt leak and
we think it plugged the radiators.

It definitely plugged the rads, but I think it was because they were at the bottom

of the system and the stuff settled there.

Since Finn is not trying to plug a rad leak, he could try it, but remove the rads
from the system first?
