I've been using DC-4 dielectric grease on my beads and they release nicely after many landings. Last year, the Sportair guy at Airventure told me using the grease can cause the stem to shear off when braking heavilly. I haven't seen any movement of the stem and the old mechanics here on the field have no issues with the Dow grease.
