Alternative to POR 15?

...more grassroots priced.......?

Its only a little cheaper, but Eastwood's POR-type stuff works great. Someone told me they used Glyptal and it worked really well.

I don't know what it costs though..

+1 Eastwood Rust Encalsulator. It does show brush strokes unlike the POR15 though. I brush it on and then go over it with a small roller.

Unfortunately, most of these products are not going to be "grassroots" friendly on the price. Quality costs.
I've used Rust Bullet, POR 15, and Corroless (Eastwood product from years ago). Bill Hirsch also has a similar product, but I've only used his gas tank sealer.

Each of the products has good points and bad points. Most have a limited shelf life even if unopened. It's a lot shorter once you open it.

I only have experience with POR. I top coat with a rattle can while still tacky and it is tough as nails. Still not grassroots though.

I had pretty good results with zero rust.

Biggest thing I would recommend is to make sure and clean off the oil and grease first. The idea behind these is less prep work, but there are some things that will make it stick better.

I have used POR a fair amount. It brushes on VERY well and leaves a finish that is VERY similar to powder coat (don't leave it exposed to sunlight though). Great for suspension or underbody without need for a top coat.

I just tried the Eastwood stuff. Probably good for what it is, but is CRAP compared to POR. If you just want to seal in some rust, it probably works, but it goes on MUCH worse than POR, and it seems like it goes on much worse than most paint. I will never buy it again.

Which reminds me, I need to order some more POR. I wouldn't mind trying Rustbullet, but after my experiance with the Eastwood crap, I don't think I want to risk it.

I like Eastwood's rust encapsulator also. I thin it a little and spray it on.

Once you've opened a can of POR, seal the top with plastic as well as the lid and bung it in the freezer. It'll last for at least a year.

I used POR on my Locost frame and on the frame of my old Land Rover. The latter has seen particularly hard use, including dragging the parts over rocks POR-15 is awesome. Just prep the surface with phosphoric acid (ie, Metal Etch from Home Depot instead of the expensive POR version) first.

The chassis saver did not leave as nice of a finish as POR, that's for sure.

I've used POR15 and Rust Bullet on the trademark rear wheelarch rust on 92-95 Civic hatchbacks. Neither impressed too much.

I think cutting and welding is the only way to fly w/ that rust, anyway.

Paint didn't stick to Rust Bullet. I'm going to try it again when I re-attack the same area in a few weeks.

You have to apply your top colour coat while the POR is still tacky. It imbeds in the POR and is damn near bullet proof

What about "Rust Converter"? I know it isn't the same type of stuff, but does it work?

I tried some of that Rust Converter on the E36 M3kicker. According to the instructions, it was supposed to turn exposed rust into a black, primer-like surface.

It didn't, instead I just got a shiny clear-coat over the rust. I ended up using Herculiner over everything. No idea if it will hold up or rust right through, but it seemed nice & solid after it dried.

I used the POR 15 -steer clear! total garbage-def not grass roots and made my project twice as long and twice as expenseive!

I have to disagree-Por 15 failed and then the company bailed on the warranty...peeled and was just the worst-stay away from it!

I agree ...i used the POR 15 and it did NOT prevent anything all it did was empty my wallet.

cut and grind...the only way to get rid of it guys

yeah try that stuff... the POR 15 that I used was trash...made my project just miserable-and to top it off when i called the company-they treated me like BS and tried to make it like I did not know what I was doing....steer clear.

So, Ray, what are you trying to say?

go with that....the por 15 is total BS-all that you read on it is put out there by the por 15 dudes...it is crap

Yeah, say what you really think

POR is a rustproofing paint, it won't repair rust.

It's not crap. I've used it - applied properly - on a couple of projects and it works. Most people who complain about adhesion don't prep the surface properly.

POR doesn't "repair" rust, it just seals it in.

I like it just as a paint which happens to work over a slightly rusty surface although I don't really use it for that much, but at least I don't worry too much if the surface is not perfectly rust free.

What I like it for is that it covers GREAT in one coat, come out super smooth, and looks exactly like powder coating when done right (just keep the parts out of the sun). I have not used it for a base coat, but I could see how spraying color on it when tacky might be very effective.

BTW- not being a paint expert, are there any paints out there that brush on like this stuff? If so, I would certainly pay a premium for that type of paint. No need to color sand when the first coat comes out perfect!
