When I messed with it the other day I have taken the shine off some of the flat part of the wheel, the kerbed bit, scrunched bit, is right on the lip. Any ideas how to make the bit I have dulled shiny again?
Any pictures?
It’s probably looking a bit like the dull finish on car paintwork that you’d get if you were to wet sand it to remove the orange peel effect (some purists/perfectionists do this - I wouldn’t dare, for fear of striking through the clear coat!). After wet sanding, the paintwork is then machine polished to remove the dull finish to get a mirror like finish.
Without seeing it, I’d say that if you know someone with a machine polisher and they use an appropriate combination of pad and polish, it should restore the shine.
If it’s only a small localised area and you don’t know someone with a machine polisher, then you can probably do a pretty good job hand polishing the dull area using a foam polish applicator pad and a product like Meguiars Ultimate Compound or Autoglym Scratch Remover. I’ve not used either of these so can’t vouch for how effective they’d be. Just be careful not to polish too hard as you may risk polishing through the lacquer!
