Thanks to all of you who replied to my questions. I am going to paint the shock arms and dog bone links with a spray can of Rustoleum Primer and then apply a top coat of Rustoleum Gloss Black.
It sounds like the rubber cushions in the dog bone links work fine with no lubricant at all, so I think I will just leave them dry.
I am now just waiting for my shocks from Robert Paul in Yoder, Colorado. I found out about Robert in another thread, and apparently he does a great job restoring shocks and has a number of happy customers. He is a little slow, but he says they are finally in the mail now and I am expecting them next week.
