Finally got my '71 250C back from paint shop, starting to reattach trim etc. Q1: are trim moldings stainless, anodized aluminum, chrome plated, or other? I don't want to polish off plating. did that on '60 dodge hub caps. The roof rails appear stainless, not so sure about some other trim pieces. Q2: the roof rail rubber inserts have shrunk over the last 50 years. I'm trying to soak them in ATF then hang them up with weights attached to stretch them out. Does this work or something else better?
