Re-doing kitchen and would like to not have to buy all new pots and pans.** A: Seriously, please do not do that. That would be extremely harmful for you and whomever else you cook for. **Q: Can I paint now and put the parts aside, then do the curing process later, after my engine is back in service?** A: do a light paint now, let it dry then paint again for better results. **Q: How high of temp can it sustain? says intermittent up to 2000°f. kinda ambiguous. can it do 1600f for 1hour?** A: i used this product on my 4 pistion calipers and tested them at my campus garage, i tested it under constant and heavy braking, it withstood temps up too 1989F. The red paint i used has been on there for 3 years and i still havent had to touch up the paint **Q: Does this contain zinc to work as a good primer for aluminum?** A: Not sure this answers your question but I can tell you from experience that this stuff really works. I used it on my aluminum engine top side and it's been 2yrs and my engine paint still look new to date. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good product if you are willing to take the time to do it right. *by on Reviewed in the United States December 16, 2017* 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. ### ⭐⭐⭐⭐⭐ Easy to use *by on Reviewed in the United States June 21, 2026* This primer lays out nice even if you are not a professional painter.
