Review: Good primer - Good product, Worked well on my brake caliper brackets.
Review: Good quality primer used for pellet smoker cover where high temps are a concern - Had some rust spots developing on a pellet smoker. I pulled the metal cover off and sanded it down to remove the rust and then hit it with this primer. Primer lays down nice and smooth and dries almost instantly. I'm still working on a stainless steel high temperature finish coat but I believe that this primer will help to ensure good adhesion and eliminate any potential for peeling or blistering for temps up to 500F that I regularly cook at.

## Questions & Answers

**Q: Can I paint my pots and pans with this? 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.
