I note in reading back GMC Motorhomes International Newsletter issues
that there was some concern about using today's popular antifreeze
containing silicone. Reportedly the silicone attacks the ordinary
solder used in the GMC radiators; newer radiators use silver solder.
QUESTION: Is this really an important issue??? Has anyone had problems
with Prestone or Zerex, both which contain silicone???
