I had all five wheels done on my Outback for £300 all in at "The Wheel Specialists" in Farnborough.
Tyres off, acid dipped, any damage repaired, shot blasted, powder coated inside and out, diamond cut, clear coated, tyres refitted with new valves, wheels invisibly balanced, three year guarantee on the finish, and all done in a day.
As good as new and a lot less effort.
