Rust Convertors

[rb1949]

Was reading/checking out the multitudes of "Rust Converter" products available, some mentioned here. Due to extended periods of moisture
in the trunk (like wet carpet) the floor pan had gotten excessively rusty. (Other owners didn't notice??)  Have since resolved water
in the trunk issues and dried things out. Rust Converter products seemed like a logical approach to try and keep this metal as solid as
it is. There sure is a selection to choose from, and a variety of prices. Some reviews mentioned a competitior brand, so I checked it out.
The name was CORROSEAL 82320 Rust Convertor/Primer. Sounded good, at a reasonable price of $21.95 for a 32 oz bottle. Plus I found pick-up
in store, no shipping. It's a milky white liquid, easy for brushing. For the inaccessible nooks and crannies, I put it in a cheap plastic
bottle and sprayed on. Simple. It turned the rust black within a few minutes, but let it cure 24 hours. It's also water based for easy cleanup.
And for areas of mixed paint/rust, it does DRY clear over paint (some do not). I'm pleased so far.
Ambition had me mixing up Rustoleum for the top coat. I finally got a 'close' match to the Blue (but not perfect). Who cares, it's a TRUNK!
The idea is to try and hold the rust at bay, 95% of it will never be seen. The paint covered the Corroseal with no problems and dried well.
Still got 1/2 bottle left, so will crawl around underneath and spray any rusted areas. Good luck with whatever product you use.

My only experience with rust converters was with POR-15,and the one I think I learned is that although it performs as advertised on rusty steel,it doesn't stick worth a damn to clean steel or steel with paint on it.

rb1949, that sounds interesting.  Where did you get it?

Since i'm dealing with this issue on my boat trailer I will give you my 0.02 worth. If the metal is rusted through, replace it and provide protection moving forward. If it is just rusty but still sound I recommend a product called ZeroRust. Its not a "converter" type product, but just provides excellent rust protection. Wire brush off the old rust, use their etch product then coat with the red oxide primer. Then you can topcoat with another Zerorust color or another type of topcoat. My boat goes in the ocean and is drysailed, which means we haul it out and goes directly on the trailer and is washed down. You never get all the salt residue and rust happens. Over the last 7-8 years trailer sections coated with ZeroRust have not rusted, period. Other sections coated with Rustoleum or standard paint have failed to the point I'm replacing the 6" steel channel the keel rests on. YMMW.

BLUE, just Google the product name/number, results show where it is available (Amazon, Ebay, etc) Prices vary. I found the best price to be Home Depot, with free ship to store for pickup. (They don't stock it.)  Being water based, and drying clear over paint, caught my attention. Just wash your hands, brush and spray bottle when done. Doesn't irritate skin. 32 oz is coating more than I anticipated.

Was underneath today, so slopped this Corroseal onto parts showing rust. Frame, floor panel, front suspension. NO pre-cleaning or wire brushing. Nice and black now. These areas will not be getting any kind of topcoat paint. It will be a good test to watch durability.

If you have a combination of rust, sound paint and bare clean metal, will Rustoleum Rusty Metal Primer adhere as an undercoat to the painted and bare steel as well?

Do you have any pictures?

Not tonight. But it's only an old trailer and I want a quick and dirty paint job that doesn't cost too much.  Rustoleum seems to fill that requirement.  Moving up to automotive primers and topcoats really isn't an option.

. . . Just wash your hands, . . . when done. . .

 

 

Don't they have a Harbor Freight in your area?

[rb1949]

Didn't see the product as available at Harbor Freight. They may carry something else. Lots to coat underneath, will need another bottle.

They don't have disposable gloves at your Harbor Freight? (My comment and link was in response to your comment about washing hands after using one of these rust converter products.)

[rb1949]

Be more clear next time. But after slopping underneath and upside down, gloves will be on next time. And long sleeves.

More clear than a link that directly goes to disposable gloves?

you can lead a horse to water but he still cannot make a good glass of ice tea

[rb1949]

The link I see in the post says H-F, nothing about gloves, so didn't click it. Never looked, does H-F have free ship to store for pickup?

Rust inhibitor by loctite is what the military uses, it is called Extend. I was a chemist at one time and a Navy Aviation corrosion specialist, I like the fact that you can see the rust turn a dark purple. I,m applying DP50 primer tomorrow. I have the bady on the rottiserie so its a great time to prime before I let it sit while I sand blast the frame and finish the frame restoration. I saw the Plymouth owners club show guide, and it has the specs for eco sheen or they call the under side color gray. Plymouth says its eco sheen, which I think was primer that had a satin finish. Any thoughts?

ACE Hardware's Prep and Etch is the same product as POR 15 at 1/3 the price.

I use Ospho (it's a green liquid)...I spray/brush it on as I sand the rust. Let it sit for 24 hours and it'll turn black. I learned of it at work when we were dealing with old rusted agricultural equipment out here in southern Florida where there is humidity daily.

I used "Extend" on my Plymouth over 25 years ago.   It worked great, still looks good today.

The past few years, I used Purple Power's "De-Ruster", that I bought at Advance Auto Parts.

Advance does not carry it often, so I called the Purple Power supplier in N.C. and bought a case,

was about $10 a quart....
