Thread: Por-15 Review

Tweet

I believe that POR15 is a close relative to powder coating, where the "sheeting" effect is great if it bonds as expected/advertised, but is a curse if it simply forms a sheet that's floating free of the surface, and heaven help you if moisture gets underneath that floating sheet, because it will hide the rust monster until the sheet breaks free. Not a fan.

I'm with roger on this, it's not something I would use again as I used it exactly as instructions and found it lifting after 6 months, luckily it was only a test piece and not a complete frame
