Recently we have helped to do some wheel repair for customers with CNC Machine Wheels.
We always advise our customers that repairing these types of wheels is different to painted alloy.
We cannot replicate the cnc lines without the cnc machine and recommend that if you are very fussy then its best to get them machined.
Otherwise the repair area will look 90% better than gutter rash, but on very very close inspection it will be clear that the repaired area has no cnc machined lines and therefore we cannot say it is a 100% perfect repair without the machining.
When considering wheel repairs on your machined wheels weigh up your budget against your level of fussy !
