I've painted my 3200 white. And the wheel rim white too. And the rudder-to-wheel springs white too.
But I must say they are mostly filled up with this fine mixture of grease+engine oil (yes, from short negative-G's!!!)+smoke oil+sand+dirt.
Have to clean that mess every week, or every 15 days !!!
Leaf springs are black, new factory ones, new style, larger than the original 1969 ones. Helped to stop shimmy issues.
