Well, if you want to get rid of the coating... don't burn it off... It might change properties of the steel if you heat it up (of course this only applies if you are using a torch). That is why they don't recommend you use a cutting torch to cut a coil off a spring to lower the front end... It might just make your car ride funny. Anyway, you have the option of painting over it or sandblasting it off. Good luck!!!
