What is por 15 ???

POR 15 is a product typically used for automotive undercarriage restorations. It stands for Paint Over Rust, the product does not work well on properly cleaned and smoothed steel. It is a very durable and tenacious product that does a GREAT job adhering to corroded steel, not to be confused with flaky delaminated corroded steel.

There is a top coat for POR 15 that is UV stable for use in areas that will see direct sun light, but the base POR 15 itself is not UV stable and will quickly turn grey and chalky if used in an area where direct sun is seen.

There are other very similar "knock off" products that work nearly identically, these would be Chassis Saver, Rust Bullet, KBS Chassis Coat and Eastwood Restoration also makes a version. Most of these are available on Amazon and readily available and easy to use.

A note, do not get it on your flesh! It will sink into your pores and you will be black for WEEKS. Ask me how I know... I did a truck frame and had a black speckled face/hands/arms for almost a month! Acetone does not touch it :-(

The coatings are very hard and the descriptive "tenacious" that I used is due to how it adheres to a surface rusted part. You can beat it with a ball peen hammer and it does not chip. You'll brush it on and it will not look so hot, but go to bed and come see in the morning and it will have flowed out smooth and looks like the part was dipped in gloss black. I have used POR 15 for many years and never been disappointed. Rustoleum is not match at all.

POR15 is also expensive, slow drying, unused portion doesn't store well, and has a strong odor.

But, it is the easiest way to put a durable coating on steel.

Its strange that the top and sides of my mmm deck are primered and painted - but the underneath flat area is just smooth metal with paint on it (not even sandblasted because its just smooth as a babies butt).

I am refurbishing an old Herd 750 spreader and will be using POR 15 The prep work is time consuming getting the rust, grease, oil, and grime off the spreader but I wanted to ensure a rust proof surface. I hope to post some pics when finished.

Hey axle hub. Just to let you know. When I worked for an ag manufacturer, the stuff we hid would blow your mind. Rusty scratched up metal would be turned so that the problems were hidden so the customer would never see it. We built alot of conveyor and if you new what the inside of the conveyor looked like it was alarming. We would take a sheet of rusty or blemished metal and then figure out what parts we could cut out of it and still hide the rust or blemishes. I won't disclose the name of the company, but I will tell you that they are one of the best at producing what they make.
