Ceramic coatings for me (have a handful of them) last depending on where I was living.
In Ohio where it's humid and moist pretty much year round I would get maybe 6-7 years out of Jet Hot coatings before I'd start to see mild pitting coming through. That was just the norm living in that humid climate.
Out here in Arizona where it's very dry, 15 years and still looking good
Lately, since Jet Hot coatings have gotten more expensive and fewer places seem to be doing it, and the fact I'd have to ship them off across several states to get it done, we've resorted to some different high temp powder coating processes as there are several places local to me. Redid dad's headers with the high temp silver powder coat about 7 years ago when he moved out here to Arizona, they still look like the day they were coated, it's held up perfectly, and the cost is much easier to swallow. Was about $300 and I can just drop them off and pick them up. Verses $700 for the last Jet Hot job I had done plus shipping them back and forth.
Actually getting ready to have 2 more sets done with high temp powder coat.
