I did end up getting the Polystrippa pictured and it works well... Used a wire wheel to scuff
Paint just falls off the shiny metal underneath... Does want to still grab the spokes which are all sandblasted judging by the texture underneath, but still comes off fine with a few coats and some hard sprays with the hose (don't have a pressure sprayer with me atm) Now, where can I buy paint from tomorrow to spray these satin black with a semi-gloss finish?
