Ed. note: Readers, please restrict public discussion to the technical aspects of the question. Our experience indicates that public brand-to-brand comparisons rarely work out well considering the anonymity of the internet and the impracticality of determining the vested interests of the responders, so we don't print them. Thanks for your understanding.

I've done some testing of powder paints applied to an aluminized steel substrate, tested up to 485 °C, as we've considered switching to powder on two occasions.
