Opinions on (or alternatives to) POR-15?

[smercier]

I've completely stripped my car down and sanded / painted the interior / trunk of the car with POR-15. I'm about to begin on the engine bay and the underside of the floor pans. Does anybody have any positive or negative experiences with using POR-15 (POR-15 and / or chassiscoat in this case) on these parts of the body?
If anybody has any bad experiences, can you please describe your prep work? I bought some Metal Ready, however I didn't want to use a product that I had to wash off with water afterwards (in general, I try to avoid spraying water on bare metal surfaces). I used various chemical strippers and a wire wheel to strip the paint off of the top of my floorpans and laquer thinner to clean them before applying the POR-15 and I've had good results.

Finally, is there anything anybody else recommends? I want to do this once and do it right. I've heard some reports of POR-15 peeling off and while I don't think this would be a huge issue issue for the top of the floor pans or trunk, it may be for the undercarriage as rocks, etc from the road may chip the finish and cause it to begin peeling.

Any thoughts, concerns, and advice are always appreciated. Thanks in advance.

P.S. Has anybody else gotten depressed when they look at what's left of their car and realize that there might only be 5 or 10 nuts / bolts left on the whole thing? : )

Try the stuff that Eastwood's sells. Can't remember the name of it, but from what I've read, if I were to use one of the two, I'd use the Eastwood's stuff even though I hate paying the markup they get, so much of that stuff you can get elsewhere for cheaper....

I think it's called Rust Encapsulater....

I used the Rust Encapsulater on my front fender wells. I just brushed it on, let it dry, topped with a couple coats of primer, and sprayed on some satin krylon fusion. We'll see how well it holds up over the winter. I don't know if I want to put any undercoating on it again, because that stuff is a real pain to remove.

i used POR-15 on my old mans cobra kit car chasis and it worked great. smells bad, we actually applied it with foam-ish paint brushes but it eats those up so we just bought a ton of them. at .50 a piece who cares

I am using Zero Rust.

Rust encapsulator is what I used with good results. The only issue I have noticed with it is that it will dissolve if gasoline or brake fluid comes in contact with it even after it dries.

I used POR-15 for my engine bay. I liked it. Its finish is pretty hard, and pretty durrable so far. (Its been on the car for 6 months, but I havent driven it, just done work in the engine bay.) Its not totally flat (like Mach 1 stripes), and its not a gloss, so I like how it looks in the engine bay. I'll probably throw some in the wheelwells at some point too, as the sealent/undercoating in there is dull and pretty ugly. Did you consider doing body colored engine bay? Gloss paint in an engine bay looks amazing IMO. (If your car is gloss outside)

I put Por-15 on my fllorpans after I replaced them. So far a year and a half into the rainy north west and no problems.

i helped a buddy of mine put por15 on the inside of a mach 1 and it worked great, i also used it on a trailer and it works great on rusty stuff, you are definetly going to need alot of foam brushes.

POR 15 is sprayable, but use a reserator, it is really nasty if you breath it. Rollers and brushs work well. POR 15, if it is not topcoated, will eventually fail of exposed to sunlight. If it is not directly exposed to sunlight, it will fad (become dull) over time. Eastwoods Rust Encapsulator needs to be top coated also. I have seen a test between POR 15 and Rust Encapsulator and the Rust Encapsulator faired better. If you have some surface rust, you might want to consider Mar-Hyde's rust converter. This can be top coated if desired, but does not require top coating like some other converters do.

I used Por 15 on my floor pans and por 15 and chassis coat in my trunk. over the winter im doing the whole undercarriage with it. but the thing with Por is the prep work is key. i used the metal ready and marine clean to prep it and it worked fine. por 15 supposly works best when there is rust on the surface

 

[smercier]

Maybe they want you to rinse off the Metal Ready with water to create a thin layer of surface rust?

I used POR a lot on my project. I know it seems weird to put water on bare metal. When you put on the metal ready it just looks wet. Then you rinse it off and can see the reaction that leaves a white film like on the surface. I used some compressed air to make sure it was dry. This is the zinc/rust/whatever that the POR sticks to and WONT peel if you have good coverage with the metal ready. Try it on a peice of scrap first to see how it works. I like it.
