Good advice. Common powder coats are polyester, polyurethane, polyester-epoxy (known as hybrid), straight epoxy (fusion bonded epoxy) and acrylics. - check your powder's service temp range AND
insulative properties! A powder coat can be quite thick, what you likely don't want.
Also, particularly on a casting, coating adhesion is a major issue. Assume you know about phosphate; sand blast if you have the electrostatic equip.
You'll want a coating w/thermolytic stability that enhances heat transfer.
Be careful! Boilin' brake fluid no fun at all!
