Default Por 15

I bought por 15 cleaner, etcher and rust inhibitor paint in the red can. Use the pro red can for aluminum.
i going to do my outdrive. I e-mailed the company and immediately got a response Buy phone,.
this guy gave me detailed instructions on doing a corroded outdrive. He said I really donít have to do much prepping of the corrosion because the cleaner and etcher will take care of it. I sanded it down anyway. And Iím still going to get most of the corroded areas clean. He said it was fine but not necessary. He said use the cleaner and etching product without cutting corners. Prepping is key. After the prepping is complete paint two Thin coats. Paint the second coat after doing a finger slide. If you rub your finger across the painted surface and donít get paint on your finger and itís still tacky put on the next coat. 3 to 4 hos. Also said it is self leveling. If itís an area that is exposed to sun it will need a top coat. The sun will break it down. You can use any kind of top coat it doesnít have to be por 15. Iím pretty sure you have to give it a 320 grit wet sand for a top coat.
so long story long. Iím doing it. I was told it will last a very long time even on aluminum in salt water. Water makes the product harder. It actually hardens in humidity. If you open the can use what you need and immediately cover the can. The humidity can start to cure the paint not used in the can. StorE in refrigerator to make it last longer.
I will post pictures of what it looks like befor during and after. I will also give updates on how it holds up through the summer (2021).
if I missed something and someone wants to add to the post do so. I only talked to him for 15 min. I can also call back if I have any problems. Very good customer service.

Only used it on steel myself. Started restoring an old car and had a couple of little spots that aren't big enough to patch in. POR-15 around the edge and all rust has stopped dead in it's tracks. Amazing stuff. Good friend of mine's father POR-15'ed the entire frame of his Buick GS twenty years ago and it still looks like the day he did it.

I used it on an outdrive about 7 years ago. It worked, looked very good, but did bubble in spots pretty quickly. I definitely had it prepped right, it was down to bare aluminum, used the etcher.

Definitely good customer service. I had an issue with heat on my 12-71 manifolds peeling the paint off. They sent me stripper, paint to replace what I used on the manifold and new hi temp manifold paint to put on in its place.

Well I already bought the cleaner etching and paint. I’m now debating weather to put it on. I read some people have excellent results and some not.
one guy said it lasted 7 years on his outdrive. Others said it peeled off. Some guy said if you go 80 mph it will peel right off. I’m not going over 25 mph. So I it’s like a mixed bag of good and bad.

Have used it on trailer parts and have mixed reviews. Bottom line is nothing stops salt corrosion, nothing. You can spend of lot of time and effort slowing it down, but there is no fix.

I bought it, so I think I’m going to try it anyway. What’s the worst that can happen, sand it down and repaint it again.

Zinc chromate is good for aluminum primer. Seen it in aerosol cans

I would be interested in your results with aluminum. I used it on my classic truck frame and it still looks great.
