There is concern amongst some that the temperatures used in powder coating can alter the strength of the wheel. If temperatures over 400 degF are used it could indeed reduce some of the temper and strength of an alumunum wheel. Some wheel makers recommend against refinishing their wheels using powder coat.
I had a set of wheels for my '95 E320 wagon powder coated a year ago; so far with no signs of reduced strength even when used on the notoriously bad roads in PA.
