Just my 2 cents of advise.
As with many things, it is not what one does but rather how it is done. I did continue to bake parts that would fit in a toaster oven I had in the shop. 200F was plenty to get the adhesion improvement I was looking for. That is WELL below any issues with aluminum.. If one reads the Variprime docs, it is above the paint service temp but I experienced no downside during baking or 6 years of service.
To your point, I am not a fan of powder coating aluminum for the reason you stated. The baking temps are too high for my comfort level.
