Ken,
Thank you - I went and searched tapatalk. Found this:
https://www.tapatalk.com/groups/cj3b_bulletin_board/springs-t2379.html which is the discussion to which I believe you were referring. Very helpful. I'm trying to call Walck's (busy signal) to find out whether their springs come with lubrication between the leaves. Seems like they must? in which case I will just spray the outside with the same epoxy primer and black single stage topcoat I used on the frame.
