CURING POR 15

People love to spend $$$$ on their ( baby) car, when they have enough to spend.
I bet IF a lot of high end paint/resto shops were quizzed about their methods, I bet the vast majority would say they do not use POR 15. High priced stuff and other methods work as well or better and cheaper. Sure the shop that charges $80-100 per hour can afford to use whatever. Bet they don't/
I really don't care. I use what has worked for me for decades. I used POR 15 once, maybe 25-30 years ago.
But like Divenut says, you must be careful treating metal with any Phosphoric acid or any acid as some epoxy primers can react and not that day either! Be warned.
