I have the streamlined Grove legs on my -8, and they were powder coated when they were installed by a previous owner. The coating has lots of cracks, all in the crosswise direction that would be caused by the flexing of the legs. It seems that the powder coating is not flexible enough for this application.

I've been told that powder coating is like a coating of plastic, and if there is an opening in the coating (like a rivet or screw hole) there is a way for moisture and dirt to get inside and corrode things. The corrosion can progress unseen under the powder coating, as it lifts it up from the metal. My IA prefers paint, and does not advocate powder coating any structural parts of airplanes.

I plan to remove the coating and epoxy prime and poly paint the gear legs as soon as I can get to it.
