Have had a set of second hand rims delivered today. They're still 16s but a more interesting style (imo). They have been powder coated black, I'm aiming for a purposely menacing look, with 40.mm drop.planned next, anyway they have had a poor coating of laquer that I want to remove, but not necessarily reapply, what is the best way of safely removing this without having to redo the colour? And is it essential that I re-laquer the wheels? Thanks.
