[DeTomaso] FLUIDYNE RADIATOR STORY

[Jeff Detrich]

Fluidyne's owner, Gary Johnson(?), has been a long time Pantera supporter.
I can't imagine he'd jeopardize his reputation over a $600 radiator,
especially since Fluidynes are working so well in so many Panteras.

I believe No Rosion additive serves the same function as a sacrificial
anode.
