Powder coating is a very durable finish on all metals, it is a electorstatic process, which means it requires that you ground the surface your applying it to, makes it very strong. As for temps under bonnet, when baked a powder coating oven is set to temps between 180 - 220 degrees Celcius, i doubt it would then inturn have any trouble under bonnet. However powdercoating is not cheap by anymeans and the surfaces need to be completly stripped of all rust and impurities, otherwise the power will not bond with the metal, and if you are powdercoating over aluminium surfaces, it will aslo require an addition prepration of a coat of etch primer, otherwise it will just not adheare to the aluminium. Last but not least the high temp enalmals that you can buy in a can, VHT make some very nice high temp sprays though if you read the instructions on the back you will find that the process of application is not just spraying it on and letting it dry. You will find that it needs to be baked in a oven for it to stick really well. Having experimented with this product i can say that if you apply it and for most of the part dry it with a heat gun you will have better results and it will be more durable than what you may have expirienced in the past.
Good Luck
