Getting my LX's going again after a long Lay Off

Both of my LX's suffer from the infamous 'Sticky Mirror Syndrome' which I can live with but also intermittent exposure problems -- then I read on www.pentaxforums.com ( Mostly YANKS ! ) that if you do the same as on the ME Super ie Rotate the exposure compensation and ASA dials back and forth many times it cleans the contacts underneath which I DID and found the exposures now agree with a Weston Master V and test B&W film came out well !
