POR15 EQUIVALENT BY RUSTOLEUM

[1993_VG30E_GXE]

Can anyone recommend a product or combination of products by Rustoleum that can do as good a job or better than POR15 standard paint.

I'm looking at this so far:

7400 System Heavy Duty Rust Inhibitive Primers

And then can I just top coat with a cheap Dem-Kote.

does it have to be rustoleum? Eastwood rust encapsulator may be a good option too.

what are you going to paint?

Hi JH - It should be Rustoleum or Dupont, as I have good pricing on these brands. For example Rustoleum offers:

V7400 ALKYD ENAMELS
V6400 ALKYD ENAMELS
9400 HIGH GLOSS POLYESTER URETHANE

I just don't know what POR15 actually is.

Tom - I'll be painting metal in the engine bay of a 93 Maxima. Some of the metal is rusted so I'll grind as much away with wire wheels, and I have something called Rustoleum Rust Reformer, but someone told me POR15 is better.

I'd look into rustoleum's industrial stuff. The urethane is probably more durable than alkyd.

make sure to prime.

The Rustoleum Rust Reformer is a waste of time and money. I've used por15 but have not decided if it works like it says it does. I heard rust bullet works good.

I have used this with good results. Found it locally at an auto parts store.

"Not recommended for automotive exterior sheet metal repairs."

Huh????

Warstud your right, rust reformer does seem like a waste. See my post in the Mechanic Maintenance forum about it.

Tom, I'll look into those. I have access only to the industrial line. I have some dem-kote stuff in stock but it's much cheaper in price than the rustoleum stuff. I'm wondering if it's [censored] - why it's so cheap.

Please see my post in the Maintenance/Repairs forum.

I have limited knowledge about painting over rusted metal and have tried rust reformers with varying results.

If you spend an hour googling rust converters, you will find a half dozen research reports that shoot holes in the claims made by rust converter companies. Most seem to be made with phosphoric and/or tannic acid. There seems to be a few new arrivals that claim to be non acid and safe. I am yet to be convinced that these products live up to their claims.

Here is one link that puts a different slant on the topic. It talks about paints that are designed to be put over rust vs. regular top coats. See his list.

Most primers/paint are designed to go over clean metal. Have you read the labels of the Rustoleum products you mention to see what they recommend for pre-paint prep?

The only Rustoleum product I know that advertises for rust application is their Rusty Metal Primer:

Good luck, and please share with us if you learn anything new.
