[AMRadio] More WD-40

[Tony Golda]

     I would go through wd-40 by the gallon. Used it in a "spritz" bottle, 
and sprayed everything down good before I took it apart. That was in the 
auto repair trade. One of the parts houses here in MI didn't carry wd-40 by 
the gallon. The guy said that the company Pep Boys, was based in the south, 
and they didn't have much rust there.
     It sure seems that the fomula changed a few years back. The new stuff 
didn't seem to work as well. I buy old cans of wd-40 at yard sales, and save 
them for my radio work.
