I don't think it would be worht it, you should be able to keep your banshee cool enough without a coating these coatings are old they have been around forever but they are not practical if they were really a good thing they would come form a company from wiseco at a cost of course, i know there are shops arounfd me that sell powdercoated and high heat coated pistons and valves and such but its just to impractical don't do it in my opinion.
