Handles the heat
Size: 12 Ounce (Pack of 1)
Used this on valve covers and it holds up to engine heat just fine. Dark grey color and dries fast. Same price as home Depot. Sprays a nice even coat just make sure you shake it a lot.

Good product if you are willing to take the time to do it right.
Size: 12 Ounce (Pack of 1)
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. ... show more

I used the primer and also the same paint on the edges of my open steel kiln, and it survived multiple runs of heat treating knives at1600. No direct flame contact.
