Rust Prevention Product Testing

[coW]

I've been following Lee's experiment as well and referred others to it. It is a very useful test.

Thanks for that link - That's quite interesting as well.

I have been following for a while as I have always used por-15. Excellent work Lee. This thread should be a sticky.

Thanks guys.

No change except the small ones are bubbling a little bit.

The consumer reports for the vw and auto world. Hopefully the test will be ongoing and ongoing. I have used Hammerite on steel wheels, both sides and had bleed through in six months. Rustoleum lasts longer than that used in the same manner. Also have used the por-15 products. Have had some bleed through which might be because only did one side of the rocker panels. Am tempted to pour product into the enclosed areas for added protection, but am afraid of wasting the precious stuff. Thanks for doing the test.

One nice test. It is hard to decide on what to use if no one has tried out all the products side by side.

No changes so far. I was thinking of pouring brake fluid on them and hitting them with a sledgehammer to see how they hold up.

Lee--
I can't remember if I mentioned this, before, but spray some sheet metal with Plasti-kote 500 degree engine paint. I have had good luck using it on all kinds of stuff.

[VWBobby]

I also wouldn't mind to see a test of the Plastikote 500 degree paint!
I use this stuff on my valve covers, brake calipers, or anywhere that I want a very protective coating that won't chip/scratch as easily as regular paint. I read somewhere that it has ceramic material in it...that could be the reason it works so well when scratched.

Excellent test!

Forgive my ignorance as a newbie, but I've got 2 questions:

1. Are any of these products sandable? In other words, if I prep/paint these on my front window frames or my rain gutter to kill rust, can I sand the product down when dry to make it smooth, then primer over it before painting?

2. What happens If I use these products on areas with cancerous rust? Do these products really "eat" the rust down to the bare metal, or just chemicaly encapsulate the rust from air - killing it's progress? I'm worried about small pinholes becoming big holes!

Thanks,
- Rick

I noticed you said only 2 hours for the POR 15 to dry- it takes 4-5 hours inbetween coats, 2 coats does it. I've both brushed and sprayed it, with great results from both. I let a frame I did sit out all winter after POR 15ing it last fall, no problems, looks great! Brushing allows me to do a little more than 2 frames, spraying conserves and I can do about 5 frames from 1 gallon, and no brush strokes. I didn't thin it for spraying either, just got a $40 thick stuff spray gun. Gotta clean it real good, or the gun is history! I've done numerous frames now in POR 15, but I also sand blast first. Having restored bentley, rolls royce and very exotic cars for over 20 years now, I can definitely say that whatever product you use, if you don't get the rust all the way out, it will come back! For Sure! So don't cut any corners thinking a wonder product is going to save your but!

No changes in the big panels. All of the smaller samples are starting to bubble pretty bad. If they had been topcoated with paint. It would look like crap.

I have them set up to get hit for 20 minutes a day with the sprinklers for the rest of the summer.

OK! I cant wait any longer....
if you had to choose now which one would you say is in the lead.
I need to do something for the pans I just installed beofre rust attacks!!

With products like Por-15, or any paint, as far as that goes, make sure that the metal is, also, scuffed up. Por-15 will peel off like tape if the sheet metal is dirty and/or smooth.

Hello, Very good test. I've used Wurth RustGuard (under my bus and in the wheel openings) in the past with good results. It's held up very well for about 2 years now. I imagine it's simular to the POR-15. Might want to try it. One thing though, it has no UV protection. Is you sample piece in the sun? Something to consider. The Wurth product is supposed to be top coated (when tacky) if it's to be exposed to UV rays.
