POR15

[Bill Lawless]

I decided to Blast the underside and use POR15 and undercoat over that.. I see a lot here on POR15 but I did a test area, and a little on top of the steering box.
I used a semi gloss black but it dried slightly gray?? And on top of the steering box it dried like a put sand in it, like 80 grit paper.. Has anybody seen this??

Bill,

This fellow (Mike M) is restoring a 911 and uses POR15 extensively. Good presentation on all the steps he uses when applying the product. He is quite the perfectionist.

I have used it a lot over the years and I think it is an excellent product. When I have used it, it has always dried to a gloss finish but one thing I would caution is to follow the instructions implicitly. It does not adhere well to unprepared surfaces even though it works extremely well on cleaned up rust. It also does not like sunlight so the underside of anywhere is a good application.

Bill,

Be sure and wear gloves and a long sleeve shirt when you're applying POR unless you want a new "nickname" like Stain or Black Finger.

[George Hussey]

It certainly needs to be top coated and will not stick well to coated surfaces, best to apply to cleaned up rust as David said. We too use it extensively in our Porsche shop

I absolutely love POR15 on blasted surfaces that have some tooth. Some tips I found out and/or learned from others over the years.

1. Once you open the can, it “goes off”. To combat that, put Saran Wrap, doubled up, in between the can and the lid.
2. You can buy 4 oz cans online through Amazon; more expensive than a pint when you do the math, however, since it’s so small you have less chance of waste if tip #1 fails.
3. Wear gloves, you will 100% get some on you, Acetone will take it off or use a pumice stone on your skin when you’re in the shower - gently.
4. Tape off edges that you don’t want coated; it’s more time upfront, but beats sanding off the POR15 later.

My experience on fresh metal is not good, poor adhesion. On rusty metal it is amazing. For fresh metal I prefer 2K primer, I think it is much better.

I have a large can of POR15 I have been using for a few years. I drill a small hole in the lid and use a self tapper to seal it when done. I use small plastic pots like those used in restaurants for stuff like dips, perfect size to use on the usual parts that get painted as the POR15 goes a long way. I use acid brushes which are cheap enough to throw away after one use.

I used it on my muffler with a good outcome but difficult to prep. For other metal I like Eastwood primer and topcoats and if rusty their rust converter or rust encapsulator products.

What a joke. If POR 15 was any good they would be using it on military aircraft and warships. NOT. I use heavy duty military grade stuff that you need a space suit to apply. The stuff they DO use on helicopters, fighter jets, etc. I don’t have to worry about discussing whether or not it works, or ask advice about it on a forum.

I am speechless.

What product?

[Mike Wilson]

Everyone has their preferred method of protecting metal. On my car, the metal was cleaned, painted with black Rustoleum then undercoated with Wurth. Others prefer POR 15 or other products. Calling one's personal preferences a joke doesn't advance the purpose of this community.

Thanks for all the input...
Can I buzz down to NAPA and get some of that "heavy duty military grade stuff"?
