Just remember that for high heat applications, most parts are either annodized or powder-coated, NOT painted. Those are totally different processes that entail some electrical wizardry and a bit of heat. The home mech would be well advised to avoid trying that on their own.
Also, go easy on the Dremel unless you're using LOW speed and NYLON cleaning discs. Don't get crazy with any of the metal brushes, or you'll run the risk of damaging the part. Not a good thing.
Carb cleaner and elbow grease is still the best method. Good luck.
