I brought a set of pristine refurbed MV2 wheels from a forum member, I think they had been shot blasted and where freshly done for sale , its been over 2 years and no complaints but as I wheeled it out of the garage this week I noticed that all the wheels have developed quite severe bubbling under the paint work, any recommendations on how to address this? does it need a particular type of refurb (my local one man body shop said he couldn't do it)? and will it cause issues if left un-addressed? they are still scuff free, so if not harmful I can live with it a bit longer.
