I am not sure so dont take my word for it but I think if you were gonna use stock paint on something like that I would use 2-3coats of hi temp primer, then 2-4 coats of the paint then 3-4 coats of a hi temp clearcoat, that way the base layers and top layers are heat resistant and will help any chance the stock paint has of surviving the higher temps.
theoretically I think it would work...but I dont know, only problem I could see is a little bubbling of the mazdfa paint between the hi temp layers.
