My method was to sandblast the leaves with glass, then skurf the leaves lightly. Then de-oxidine 624, then apply molybond 122L, this is a dry bond, molybdenum disulfide lubricant, just that it is Australian made for us Aussies. Other USA brands have been mentioned here as well. I left the paint until after assembly. I wiped the springs down with MEK then painted with PPG7233 primer and finish with PPG Autothane black. I feel the dry lube is better than wet lube as dust and dirt does not stick to it, as well as it will fill small deformations in the mating surfaces with lube.

If you use graphite powder, mix it with a quick dry solvent and paint it on. The solvent will evapourate, leaving the powder where you painted it. This is how we lubricate the flap tracks of kingairs.
