Head gasket repair.

[CptClinac]

Hi guys,
Just confirmed a leaky head gasket. Only very slight leak and it's been stable for months.
Probably the ideal candidate for ...
GUNK...
(Rislone head gasket fix)
Anyway added a bottle of VERY expensive sealer to radiator.
It seems to be holding.
Anybody have experience of this stuff (or similar).

Thanks
Dave
