Just wondering what experience people have had using this. Especially brush application? Getting so difficult to find an affordable painter these days!!

Les,

I have used POR 15 with a brush. It goes on a bit thin so 2 coats are desirable. The POR literature says it will "gray" with exposure to UV light. It WILL. Thus, a top coat is needed to prevent UV exposure. I thought it would be good on a frame. Under the body, with minimal UV exposure and very few would ever see it under the body. It did gray somewhat. IF you are looking for rust prevention: First, ALL the existing rust must be removed/neutralized. You will need at least 2 coats of POR to build up to the advertised rust prevention as POR is kind of thin. READ the literature.

I have also used Chassis Saver. I prefer Chassis Saver over POR 15 for ONE reason: It's thicker. I had a trailer frame I needed to paint. I roughly wire brushed to remove the "loose" rust. I neutralized with acid, rinsed with water, and let dry. One coat of Chassis saver did a good job for as long as I owned the trailer. It "grayed" a bit, but noticeable to only me, as I knew what it looked like freshly painted. When I have to replace the decking on my current trailer, I plan on doing the same treatment to it.

WARNING: WEAR GLOVES! Wear the oldest clothing you have. Anything you get POR or Chassis Saver on will be that way FOREVER. You will NOT get it off of your skin. It will eventually fall off when you shed your skin underneath. ASK ME HOW I KNOW. I didn't get adequately covered and got a bit on me. They say you can clean the brush. I wouldn't worry about it. I used a Chip Brush to paint with and just threw it away.

I suggest you paint something as a test to see how the paint goes on, how brush marks level out or not, and how it feels. POR felt like water while Chassis Saver was "more" like paint but still somewhat thinner than regular paint. I found they both dried quicker than published. BUT, that was in Colorado with low humidity. I did not test the curing time as I didn't care. I can tell you, the Chassis Saver barely scratched as i slid decking boards into place. I did NOT check the POR hardness after the cure time period.

I hope this helps you out a bit. Good Luck,
Terry

Thank you for your input

Les, You are most welcome. We ALL benefit from the experiences, each of us contributes.

Imron is still available, but Dupont doesn't make it..

Terry,
Where are you getting the Chassis Saver?
Looks like its all on line
I have a trailer and was planning the same treatment,
Thanks,
Kevin

Kevin, I believe it was on line as well. I know I bought some "rust" paint from an automotive paint store and some on line. I just don't remember which was which now. I remember both purchases were easy but I thought the prices were a bit on the high side.

ANOTHER THING: Store your opened paint by #1 place some plastic food wrap over the open can with plenty of overhang, then put the lid on as normal OVER the plastic wrap and put it all in the refrigerator. The plastic wrap will keep the lid from cementing itself to the can and the cool temps in the fridge will make the paint stay usable longer. I have kept some for a couple of years and it was still as good as new. I don't know how long this storage works, but it was good for 2-3 years.

Good Luck

I used the POR 15 on the inside of WWII jeep two parts wheels. After 10 years, the paint is still glick and glossy, but it never sees daylight. It is a two part system and the shelf life, from memory is two weeks after opening if not mixed and much less after mixed, so you are doing a lot of mixing or throwing a lot of unused paint away.

I painted my entire engine with POR15 gloss black. It's tough as nails. Still looks great 7 years later. Just be careful not to get it on stuff you care about, it has incredible adhesion. And clean everything really well. I usef 2 cans of carb cleaner on the motor after I got it clean. Nothing like carb cleaner to eliminate oil (and everything else) from anything and everything. Just don't get it in your generator.
