It can be done, so use some Autosol and brasso on the crown. I did with a pair of Indy SL's last year and it worked a treat.
As for the legs, strip them back and give them a fresh coat of paint. Mags do have a habit of losing their paint, so give it a go.
As for the action, try an oil change and whack some more air in them. If this doesnt work, TF Tuning may be able to help.
