There are other alternatives. Some like GunKote (a spray-on, oven cure paint). There is nickel plating. Parkerizing is not that expensive and can be done on the grill (there are even youtube videos showing how).
Or, as I did with one, go to Wally World and pick up a can of Krylon. Touch ups can done later if needed, and curing is just letting the thing dry for a couple of weeks.
