Be specific.  I'm still waiting for the feedback from Dan Reeds post last week __________________________ Don't misunderstand friends. When I spoke highly of 8:1 Naptha/mineral oil it was for humidity laden sluggish centers. It does nothing for verdigris. Neither does Protek in my experience. Howard S. Rosen, RPT </BLOCKQUOTE> Howard No matter what solution you put in the bushings with verdigris, there is no product that eliminates it. All these do is allow the pin to rotate in the effected bushings. Some allow this to go on for a few months, others for just a few days. My personal solution to action parts with verdigris is to get rid of them. Some techs have gone to the trouble of rebushing flanges, etc. But for my money, in the long run it is not only cheaper to get new parts, but they wil work much better too. Willem </HTML>
