[ARC5] BC-459 Frequency Jump

[Clare Owens]

I'm sorry Mike.  The bottle I have says Cramolin R-100L but it is at least
20 years old.  I guess Caig has renamed their products D for Deoxit rather
than the old ways with R for Red and B for Blue Cramolin.  I just tossed my
old bottle of the Blue since it had separated into blue and clear areas and
would not mix. But the Red is still fine.
