POR 15 is interesting.

I've used a shit-ton of it. Honestly, I think it's over rated for the price.

What exactly are you using it for?

>>15448507
Not OP. Do you prefer something else?

>>15448541
There's a boat load of other rust preventative products out there. quite a few are abetter bang for your buck then POR 15 IMO.

The question is what your goign to be using them for.

>>15448489
None of the professionals I've ever spoken to use this stuff. It's always 3M, Wurth, Bilt Hamber etc etc, never POR15

>>15448734
Probably because it costs more. So it has to be better.

it's a one-pack polyurethane tinted with carbon black that has a catalyst/hardener functionally similar to superglue.
it has no rust-curing or rust-preventing chemicals; it's waterproof until you scratch it, that's literally the entirety of their claim to 'stop rust'
it's a home remedy for people who can't or won't commit to shotblasting and hot dip galv.

I know some people who swear by it but I've never used it myself

I haven't used POR 15 but I've used other rust converting epoxy primers.
They all work.

why is it alcohol based instead of oil?

>>15448489
Just do WaxOyl and be done with it.

OP here I was thinking of using it on the frame rails and cross members of my truck so it hopefully won't rust to pieces.
But I live in WI so it's probably an exercise in futility.

After a small amount of research I've found that rust paints don't actually do much if you're applying it to a chassis that's already starting to rust. It creates an almost enamel coating over the metal, and once permeated water will seep in and have no where to escape thereby cause rust underneath the coating. For this you can use anything, Por15 down to a regular bargain brand rust paint is all the same. Maybe for a body off restoration where you can bring the rust down to bare metal, these are good products. Any paint or "epoxy" is bad for those reasons.
The best way to stop rust is an oil based spray that never dries. It will constantly displace moisture. The only problem is you have to keep applying it every 6 months or year, because eventually it disappears.

>Paint runs off

Defiantly not doing a body off restoration. It's a 94 Dakota with about 200 thousand miles. So most people wouldn't put much money into it, problem is I love damn thing. It's all just surface rust except for one spot on the driver's side under the cab there the bottom is rotten for about 2 feet but the sides and top are still solid.
