ACF-50 = good stuff, I drilled 1/8 inch holes in my gear legs and sloshed  then drained and sealed with epoxy.  Control tubes ditto..  Have had no problems with corrosion, obviously it's easier to do at time zero, before installation, but effective if you leave a bit in the gear legs and let the up and down slosh it
Corrosion Block another good product but fairly viscous in compared to ACF-50..  Don Skeele 235/320 320J 650 hrs     Don Skeele    (503) 769-2563
