saw an interesting tip on maintenance of leaf springs. They said to remove rust from the exterior with a wire brush, then paint the springs with rust prventive. Then when dry you apply a layer of grease to the spring frcing it in with your hands, and wrap the whole thing in duct tape for awhile. After driving it for a few weeks you remove the tape.
Suppose to improve the spring performance. Whaddayathink?
If nothing else they look better cleaned and painted. But with what a spring goes through it seems like a waste of time to grease them; failure is usually from breaking or losing their arch. With the pressure on them I don't think the grease would really penetrate too far between the leafs. If you want to lube them use a spray lube that will penetrate and not attract crud as much.
