Well, I got my lca out. knocked out the ball joint (and almost myself when the socket flew up and hit me right above the eye)

I knew I should have spent a little more time looking for my face shield. Anyway. The LCA isn't extremely rusty, but was thinking of painting it with something to help protect it. I've seen a zinc/galvanizing type paint used. I have some rustoleum here and some 'rust former' primer by the same brand. Would this be ok? Is there a reason not to use this stuff?
