P.S. Just remembered what one of the results of overuse of MEK can be. In the case of my good buddy it was called peripheral neuropathy. This involves the use of the hands and fingers. You only have to imagine what that means to a guy that built all sorts of models for most of his life. For the last two years of his life I built and rigged his planes and sailboats. He could still fly and sail RC but his mishaps became more frequent as time went on. I did a lot of repairs but was happy to do it. Just be very careful.
