Caution: Powder coating Cast wheels
I have seen cases where people want to powder coat their cast OEM or aftermarket wheels. Also I have seen many of the same wheels being sold in the marketplace after they are powder coated. I have no goal to ruin the business for any members here but this is a serious issue.
Cast wheels are not strong enough to withstand the extreme heat of powder coating. There is a good chance that the wheel will develop a crack in the weak spots (spokes usually) and eventually break. If you are buying any wheels that were powder coated outside the factory double check to make sure they are not Cast.

So to say powder coat is what caused a small percentage of problems can't be factual... there is a strong chance that other factors are what caused the problems.
Getting an OT thread back on topic
my OEM cast were PC'd twice - back-to-back well less than a year after I purchased the car... I ran them for over 2 years with zero problems.
It very well may have to do with the process... A Cast wheel will out-gas when baked in the over... a good powder coated will cycle it first to allow for out-gassing (if you don't do this prior to PC there will be blotches in the finish from out-gassing)...
So maybe if the process isn't correct - or as stated earlier, the temps aren't right - you could have problems... hell, there are people that powder coat certain parts at home with their own kits (no thanks).
Take it to a reliable powder coated and you will be fine.
BTW - The sun causes cancer stay out of the sun.

^ I agree that there may be many extenuating circumstances. (e.g. curb rash)
But that, in of it self doesn't rule out PC as a potential problem if miss applied.
I think the long & short of it is; use a reputable shop that has experience doing wheels.
