I found POR 15 and used it on a 2005 Jeep TJ frame. Looks like new. Paint right over rust and this stuff will never come off. It worked amazing if used as suggested. Anyone else tried this stuff. ? Now I will use it on my utility trailer, tractor deck, trailer hitches, etc. Love the results.

Rust Preventive Coating

 

I bought some and used it back in the summer of 2007 at Andrew's suggestion when he brought the rust under the door seals problem to our attention. I need to pull the seals back off and check them but haven't taken the time as of yet.

 

Jeep TJ, new car in the stable?

 

Its for ripping up the ranch. Fixed it up so much and it looks so good with the frame painted et al that I just cant abuse it now. It looks new.

 

Yep, discovered the product years ago. Used the "dark grey" colour to paint both the intake and exhaust manifolds on my antique Volvo.
