Has anyone used POR-15 Metal Ready? Oily film residue?

[rennch]

I've got the Project 69 down to bare metal, and have some POR 15 Metal Ready on the shelf to treat the metal. Someone just told me that it's rumored that Metal Ready leaves an oily film on the metal which might interfere with the paint. Has anyone had any similar experiences to this?

I think the instructions call for a rinse after metal ready.

[rennch]

Yes, I had assumed that part.

I have used it several times. You need to use the metal ready or the POR will peel off. The metal ready will leave a white powder film. It should be rinsed as stated. I have never heard of an oil film. If the surface isn't etched (like the metal ready) then it isn't worth the time applying the POR.

Just about to tackle some of this, what do you guys "rinse" with?

[chatas17]

A hose with a wet rag. You want to rinse especially around any seams. Don't be surprised if the white film is still present after you rinse. That is ok. Trust me on this one. I have used the metal ready on several cars. It is the "etch" for the metal. As long as it won't rub off with a rag, you will be fine.

Thanks, just seems a little strange to introduce the enemy this late in the proceedings, guess you just have to give it plenty of time to dry?

I have used it with good success. Use as directed, rinse, then I dry it with a propane torch or a hot air gun. Do not leave it wet and sitting around waiting for more rust.

I am the one that perpetrated the oily fact. I have a POR distributor in the next town. He is the one that told me to not use the Metal Ready in favor of something use of the phosphoric acid nature. He also restores old Pontiacs. The Jaguar guru says the same. I'm sticking to using The Must for Rust and I don't rinse, but I do clean with metal prep.

The one thing I agree with is why use the enemy after all that work? Some areas are easier to deal with than others. Up inside a subframe, I'm not shooting any more water, OK? Of course, YMMV.

[dweymer]

I never noticed the film on mine. Valid point on the water-I was not doing any areas that would trap the water.

[ncseahawk]

Rinse as directed, I used a squirt bottle and sponge to get to water trapping areas.

My reasoning was that although a bit of a pita, if I did it right the first time ...

Worked out well for me.

Good luck

I have just used some simple green and then rinsed it off and never had a problem with POR15 sticking. In fact I have just put it over freshly wirebrushed rust and it still stuck on there, its tough stuff.
