*Hello Bob,*
* Where do you purchase Cramolin these days? My supplier
told me that the EPA had caused it to be pulled from the market because it
contained 47% Trichlorotrifluroethane. I find that DeOxit works,but one
formula in their line uses Naptha as the solvent. This is Not Good for some
switches made of plastic. I clearly remember when TV sets changed from Real
Tuners, with channel strips, to Rotary Encoder/Switches. That good old
Tried and True tuner spray which had been used for decades, sure would mess
an Encoder/Switch Up. To reword my question, can Cramolin still be
purchased with a professional license?*
