Rust-Oleum 248903 Automotive High Heat Spray Paint, 12 oz, Flat Black

I purchased this high heat clear spray specifically to seal my diamond art pieces, and it has worked beautifully. I use it on hotplates that I make for personal use and as gifts, and the finish it provides is exactly what I was hoping for. It goes on evenly with a smooth spray and doesn’t leave behind a cloudy or heavy coating. Once dry, it gives a nice protective layer that helps keep the diamonds in place without dulling their shine. I was especially pleased that it didn’t cause any discoloration or damage to the adhesive or drills. Another thing I appreciate is how durable the finish feels. It holds up well and gives me confidence that the pieces I gift will last and stay looking nice over time. Overall, this has become a reliable part of my crafting process. If you’re looking for a clear sealant that protects without taking away from the sparkle, this is a great option.

I do not know why my Honda Rebel came with a chrome exhaust but this fixed that real quick. A quick sand and a couple coats and it turned out perfect. It handles the heat really well too since I ride for hours at a time and that exhaust gets seriously hot. Looks amazing now and for the price it is a great fix.

Used this on my wood burning stove that was starting to get a bit rusted. Went on well, looks good. Hasn't burnt or flaked off yet. Was a little stinky the first time (but it's inside, so what do you expect). Overall very happy with the appearance. And had good coverage as well, wasn't super thinned out.

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.

Works well

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.

I have a gas fireplace and after 20 yrs, on the inner frame around the glass, the paint started to peel. Looked bad, wife mad. So did a lot of looking to try and match the paint color and ended up with this paint. Mistake, this paint is flat and my fireplace has a low/medium smooth finish not flat but not glossy. That is what I would have done different is try to find a low or medium glass instead of flat. When I stripped the paint on that frame I seen the manufacturer did not prep the surface, it had a vary smooth steel finish. I wondered how the original paint did not peel up sooner. I sand blasted the frame with coarse media, so the new paint would stick and sprayed on 2 medium coats. Looks great aside from the vary slight difference in finish and the color is not a perfect match. This paint being flat and the paint on the fireplace having a smooth low gloss finish. The difference is noticeable but does not look bad. Wife happy, life is back to being good.. lol. Of course it is holding up well so far, only a month and handling the heat of the fireplace so far, but I can not comment on longevity or endurance. I'll update this review in 20 yrs.

I've noticed that when you're applying the clear coat to polished steel it's best to make sure it's done with a vey low humidity level, or water vapour in the air can get trapped when its applied causing the metal to rust under the clear coat. Other than that lesson learned, it's working great for the exhaust system.

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.
