I was amazed at how thin the whiskers are and it seems like most circuits
would clear them out unless specifically designed not to.  Are Toyota
circuits that low current?

These are very interesting articles. The problem of maintaining the current
crop of premium radios is going to become very much more difficult as the
years go by. Enjoy them now! What is perhaps sad, is that the whole
changeover to Pb free solders is based on misinformation about Pb leaching.
Ah well ....
