I managed to buckle my already buckled wheels a little more the other week
After 1 month making them look like new again 
So this time around I decided to have a specialist paint the new ones. I found this company: http://www.wheelrefurbishing.co.uk/
They charge from £25 and upwards for powder coating per rim
That includes minor kerb damage & buckles! Mine are being picked up this Friday and I am also having the fellow stuff some 17" Goodyear Eagles GS-D2's on while he's at it.
Finally if your within a 40 or so mile radius they will collect & deliver the wheels to you
