All,

 GC Electronics (General Cement) used to make a apray by the name of 
 'Tun-a-lube', but I havent seen it in a long time.   I'm not even sure
 if GC even exists any longer.   But in the past, I have used WD-40 as
 a suitable substitute.  Some may not agree, but I have had excellent 
 service from this chemical.   And it's available almost anywhere at a
 cheap price.   Just my 2 cents worth.   Try it if you want to.   I think
 you'll be pleased.   

 And about the tuner cleaner comment below about it collecting dust in 
 the air, while it may be tru, I haven't had any problems from using it.
 But then again, I havent used tuner cleaner in a long time.   Not since
 switching to WD-40 anyways.


                                              Regards,

                                               Jim
