[Sneap] water leaks Quad coils

[Chris Westerfeldt]

David,
    Many, many years ago, a small leak in a magnet or quad coil was repaired
using automotive radiator stop leak.  They circulated a solution of it
through the coils for an extended period of time with a small pump until the
leak was plugged.  As far as I know that repair was permanent.
