Pros: resists high temperatures, easy to use
Cons: somewhat expensive, does not match high-gloss enamel surfaces
The Bottom Line: I found RustOleum High Heat Black brush-on paint to do everything the maker claims. Heck, it outlasted the grill I used it on!

| scmrak's Full Review: Rustoleum High Heat Brush On Black |
Rust is a regrettable fact for owners of barbecue grills: no matter how carefully you cover your baby, windblown rain and snow will find a way in; and in climates such as Houston's the high humidity creates condensation on anything left outside overnight. When the Ms shelled out several hundred bucks for a gas grill (no comments, please, from ‘cue snobs), I figured it would last much longer than the hundred-dollar Lowe's model it replaced. Alas, I was mistaken: oxidization cares not a whit about price tags! After three or four years (and, admittedly, having been moved twice) there were telltale bubbles and even little brick-red spots in the finish. In the hopes of extending the life of the grill, I did a little research and found a product that I thought might do the trick: RustOleum High Heat Paint. Unlike many people I dislike spray paint, so I bought their Brush-On Black. A similar product is also available in several colors of spray paint.
RustOleum states that this enamel paint is safe for use up to temperatures of 1000 degrees F (about 540 degrees C), which makes it ideal for use on grills and stoves; as well as engines, radiators, and other metal products prone to high temperatures. The paint can be used either indoors or out, and dries to a satin finish. As are other specialty paints, high-heat paint is rather expensive: expect the cost to be as much as one dollar per fluid ounce.
I used the paint on several rusty spots of the Ms's grill; including lid, pedestal, and the cast-aluminum base; following the instructions to remove rust and paint flakes as well as break the finish of glossy paint. RustOleum warns that Brush-On Black should not be thinned, that it must not be used where it will be in contact with food, and that it should not be used where it will be directly exposed to flames. Exterior surface use is fine. The resulting satin finish turned out significantly duller than the glossy enamel of that grill's lid, but matched well on the other surfaces. The liquid had a normal paint consistency, and went on smoothly with a decent quality brush. Cleanup of this oil-based paint required the use of mineral spirits, and I never did get the brush clean - of course, I never get any brush clean, so that's probably not a reflection on the paint!
The grill lasted another two years before being junked because the manufacturer could not supply replacement grates (what a waste!). The paint was holding up just fine when the trash man hauled it away, with no rust breakthrough and no flaking. Though I doubt that six bucks spent on high heat paint extended the life of that particular grill, I'll certainly try it on the (inexpensive) replacement when - not if - rust spots appear.
