I've been using DC-4 dielectric grease on my beads and they release nicelyafter many landings. Last year, the Sportair guy at Airventure told me usingthe grease can cause the stem to shear off when braking heavilly. I haven'tseen any movement of the stem and the old mechanics here on the field haveno issues with the Dow grease.TheoGlasair IIRGCessna 170A--For archives and unsub http://mail.lancaironline.net:81/lists/lml/List.html
