Perfect for my needs
As someone who builds "Alpha/Romeo 14+1 pew pews" (IYKYK) I wanted something scratch resistant and rust proof to protect my yeet tubes. Cold bluing is ok, but leaves the steel still vulnerable to moisture and surface rusting. Since the yeet tubes will be subjected to a ton of heat, I chose this particular product. Couldn't be happier. 3 coats went on super smooth, dried evenly somewhere in the ballpark of semi-satin (?) ...less than satin, but not quite dead flat. Zero runs, dries fast, and way better than a lot of other brands I've tried. I think I'll be using this product on all of my boomstock yeet tubes from now on. Couldn't be happier! Professional look, finish, and texture at a fraction of professional smithing costs!! I even recommended this to a bunch of my outdoor enthusiast buddies and vet friends! Now they plan to do the same! Pros: even coverage, smooth finish, near-flat like I wanted, zero runs, cheap and easy, dries fast, easy application, durable and more scratch,/rust resistance than cold bluing Cons: -(/) Just do it if you're a 2A supporter who enjoys slinging lead.

This paint is awesome
This paint is amazing. It covers very well. Looks very smooth and applies a lot. I am very happy with it. It made my rotors look much better than you my tip to you is put the spray paint in a bucket of hot water and your coverage when you spray it will look a lot smoother and better and professional.

Solid paint
Worked great on my brake caliper brackets, I did the heat treatment process by wrapping them in foil and putting them over a fire, worked good.

Top-Notch Quality That Stands Up to Serious Heat
I’ve used a few high-heat paints before, but Rust-Oleum’s 248903 is by far the best quality spray paint I’ve found for automotive parts. I used it on my exhaust manifold, and it handled the intense heat like a champ—no peeling, cracking, or fading even after weeks of heavy use. The finish is smooth and professional-looking, with a rich flat black that doesn’t look cheap or flaky. Application was easy, too—the spray came out evenly with no annoying drips or clumps, which can be a problem with lesser brands. What really impressed me is how durable the coating feels. This isn’t just paint; it’s like a tough ceramic shield that keeps my parts protected from heat, oil, and grime. It definitely gives me peace of mind knowing my engine components are covered by something that can really take the heat. If you want a high-heat paint that delivers on quality and longevity, this Rust-Oleum is worth every penny.

More gray than black..
It doesn't dry black. It dries a dark gray. It darkens slightly after heating, but never achieves actual black. Think more charcoal. Attempting to get a reasonable reply after asking a question to anything remotely automotive or decorative when it comes to maintenance or rugged use on here is really rough. A question asking about the actual drying color of the paint got back immediate replies stating it to be black, and not answering my question. Thought this might help.. It isn't a bad color, but not quite what I needed, as I was trying to color match some motorcycle pipes that already had older paint on them.. Which is admittedly a tough call. This isn't too far off, as that paint has too grayed a little. Paint adhesion after heating seems actually pretty good. Better than I was expecting considering some of the reviews saying how delicate it is. Nozzle semi-blocked permanently for second use, causing drips. Thinner wouldn't move it.. Next time, I'll remove the nozzle between sprays and put it straight into thinner. Used effectively to spray a chimney cap to hopefully make it less interesting to birds than the bright steel surface. Cleaned and lightly scuffed, and cleaned the surface again.. The end result was a really very nice matte finish. Again, nowhere near black. A charcoal dark gray. The stuff dries incredibly fast. When applied to a larger surface I can see how the paint rubs off more than the small test piece I did. It's going to bake to all hell on the roof, so I imagine it'll get a good chance to cure. Might follow up with some pictures next spring of how it's fairing.

Works Well
Used to paint the rust on my 2004 Polaris Sportsman 700 EFI exhaust system. So far the paint is holding up well. No rust has returned. Recommend

Rust-Oleum 248903 High Heat Spray—Durable Protection for Brake Discs
I applied Rust-Oleum 248903 Automotive High Heat spray to the brake discs of my car. The paint was easy to use and gave a nice, even black matte finish. It dried quickly and adhered well to thoroughly cleaned metal. After several weeks, the treated areas remain rust-free despite exposure to heat, moisture, and road conditions. Rust Oleum hight heat is great for protecting and improving the appearance of brake discs on non-contact surfaces. It resists high temperatures and maintains its protective and aesthetic qualities

Best ever product. Very good for rusted exhaust pipe and exhaust muffler. Just clean whole exhaust unit and apply one coat first. After 20 minutes apply second coat. Definetly valve for money product.
