If forged wheels are failing from being powder coated then I would guess that the blasting is more likely to blame. Any abrasive blasting creates numerous little stress risers on the wheel's surface. This is very different than the nice smooth finish that forging leaves. I wouldn't used anything but mild bead blasting, and even that should be used with caution.
The stripping, blasting, and masking are where the cost is when pc'ing wheels. There would be no big advantage to having these done along with my parts that go straight to degrease and on to paint.
