I've got a pair of suspension springs to clean for painting, so my two options to clean the old rust and paint off are either abrasive off a roll like this
or by grit blasting using crushed glass. I know its not likely to happen but is either method likely to leave a surface less prone to cracking, of isnt it something to worry about.
