Rust-Oleum249340 Automotive 12-Ounce High Heat Primer Spray Paint, Gray

Used this primer on my wood burning stove when I reconditioned the outside. Really bonds well and did exactly what I needed. Dries fast- perfect base coat for the other high heat paint I used. Rust prevention was Meh but honestly I probably just didn’t do a great job removing it from areas. Overall worth the purchase. I’m nitpicking

Easy to use

I used it in my fireplace to paint over the soot covered faux brick panels. I worked really well and has withstood a full season of use.

Used to prep my fireplace door for painting, went on very good and was a nice base for the black finish.

Sprayed nice and left a clean finish on my burn barrel. Did a fire a few days later and no issues with the heat. Unfortunately I slacked on the prep and the surface rust is coming through after a rain. Lesson learned. Will sand it all down and buy another can and try again

All Rustoleum products work great!

Works very well when certain common sense best practices are followed. Clean the part thoroughly, that means basic and acid washes beforehand, rough up surface (I used 60 grit) where applicable. Once clean always hold part with hanger or clean non-powdered gloves, after first coat, the same precaution needs to be adhered to. Coats should be thin and consistent. Ideally I would not move forward to final color coats with anything less than two complete prime coats. Part of the reason I coated my exhaust is that I am moving to a winter salt state, soooooo yeah, coat it or watch it rust into oblivion. I tend to go overboard on everything, so the whole system has 4-6 coats of primer depending on location and base metal, with 1-3 curing cycles (where possible), prior to color coats. Coverage is actually pretty good. After the priming process I sanded again after curing but prior to final color coat. I used black, but I imagine most colors (which are in no way true to color expectations or vibrancy... this stuff isn't jet-hot) will hold up the same depending on application and part cleanliness throughout the process. If applied and cured properly I see no reason why flaking, delamination, or "chipping" should be too much of an issue within reason. I'm a year into this job and as of my last oil change, I was able to fully inspect my work and found none of the above. I am happy with the product so far and it worth noting, this is NOT a thermal coating, it is purely protective.... and i suppose aesthetic for some. Time consuming to do right, but if the purpose is to protect your investment, well, take the time and do it right. Can you just go to town on an exhaust part and throw it on the car? Sure. Will it be as durable? Probably not. Take all of this as you will.

Decided that I wanted to do a little project on my Dodge Durango didn’t really wanna go caliper covers because in my opinion those are ugly and tacky but that’s just my opinion so I decided to paint them. These are great primers especially for high heat as hot as the calipers will get
