As with most things in life there’s Theory vs reality. You can read all you want, but nothing replaces on the job training. I’m preparing to clean and paint the frame of my Commando. I’m almost fully decided on using POR15, but I’ve never used it before. I’ve read several instructions and write ups but I’m still wondering a few things.

1. Is this a good choice for the frame?
2. Is it realistic to think I can open and close the can several times and expect the material to last? Or is this a be prepared to paint all in one session kind of deal?
3. Aside from degrease, metal prep and top coating for areas that are exposed to direct UV, any other tips?
4. When I get to restoring my Tub, would you consider using it as undercoating?
5. Best brushes/sizes, rollers, other tools to help?
6. Anything else you discovered along the way.
 
This is the internet. Everything works just like we say it does.
 
I did my M715 frame 20 years ago....wirebrushed off all the loose bits, then painted right over rust & old paint. It's held up remarkably well. Just faded out because I didn't topcoat.

And no, you can't open and close a can (unless it's maybe the same day or maybe two). At least with formula/mix from 2000-ish.
 
Coated my 62 chevy frame entirely in it And topcoated it.


Worked great and was slick as a babys ass, where before it was rougher than a moab "slick rock"

Also coated Buttercups frame partially with it. Same results.

I've used it several times and had great results.

1. Absolutely
2. I've had success in reusing a can numerous times. The trick was you have to use suran wrap between the can and the lid. I.E with the open can, clean as much of it off from the groove as you can, then cover the top with suran wrap, THEN put the top on
3. I never prepped the metal. Purple power, power wash, let dry. direct application.
4. I've never used it on sheet metal on the underside. My fear was trapping moisture. I don't like undercoting at all for this reason. I just spray bomb. But coated the firewall, frame, gas tank....etc
5. 3" brush worked well for me. Along with a big bag of 1" foam brushes for tight places. LOTS of plastic on the floor, and gloves. Get nasty with it. It will not be a clean application. You'll get it on the back side of your arm and not know it...and transfer it everywhere
6. You really DO need to topcoat it. Some get lazy and thing the sun will never hit it..but it will fade it over time.
 
Some good info in here. I have a question. Typically how much was needed to do a truck frame?

I used about a quart per frame rail and a quart for the cross members and tank. Then another quart on the firewall and inner fenders
