I’ve used POR 15 since the mid 1990s and have had great success. It’s my go to for chassis parts. As others have said, it’s ALL ABOUT THE PREP WORK. Take your time and don’t cut corners. I always media blast all parts, clean/degrease thoroughly, apply the metal prep and thoroughly rise it off. And the final step is to only apply POR 15 when the parts are thoroughly dry. In humid weather I’ve even used a heat gun and propane torch to drive moisture out of smaller parts. I’m always amazed at how much water drips off of a part when you warm it up.
Yea, it can be a bit of a pain to use, but worth it in my book. Keeps out of the bars! 😜
