That rust converter stuff.
Does anyone know how well that rust converter stuff works in a spray can? It says it converts rust to something else (some kind of hard protective coating?).
Are there any downsides to using this to get rid of rust? Mainly I am looking for a temporary solution until I can get enough time and money to strip my 71 down to the chassi and paint it. If it's not BAD for my truck, I would probably just go over the whole thing with a few cans because right now it's like 3 different colors, and I would rather have a splotchy black covering the whole thing then puke green/ugly burgandy/crappy blue/rust spots.

i'v tried alot of the rust converter products in different applications and never had much luck. the areas eventually rusted again or the product flacked off even after extensive prep and painting. i'm using por 15 now and it seems to be extremely durable. it is expensive ,about $99 a gallon, and it is also fairly toxic. i'v been hearing about a product called "zero rust" that is supposed to be cheaper and safer i may give it a try.

From what i understand some of the rust prevent paints suggest not using a rust converter claiming may cause chemical reaction effecting the paint/top coat adhering to the bar metal. Have tried 'Por 15', and couple other rust prevent products. Currently testing out the 'zero rust'. Too soon to tell.
Have done frame off restoration, seems rust eventuallly will surface. Trick is finding right combination to delay process as long as possible. Looking at 'por 15' again for the next frame using the rust prevent first, then follow-up with their top coat. Seems kind of expensive, may pay off in long run. Waiting to see how the 'zero rust' works first.
good luck,
dave

When deciding on a topcovering, you might take a look at these pictures that Len Stuart did. He did a field test between Por 15 & Zero Rust, exposing them to salt water conditions for 16 months. BTW, the pictures are located at the bottom of the page.

Aekisu, what a web site, at least for me, could have spent hours browsing the various info forums.
Wondering if the 'picklex 20' and the powdered 'prep step' are interchangable. If so, seems the prep step would be cheaper way to go.

Don't quote me on this but if I remember correctly, they are different animals. It seems the 'prep step' is a metal cleaning product while 'Picklex' is a metal/rust treatment product.
Picklex is a product like Metal Ready (by Por 15), and Rust Mort. They etch metal and convert rust. I haven't used Picklex personally but I know Len swears by it.

Our local fertilizer and chemical dealer uses Zero Rust, they are actually the largest user of it in the US. they swear by it, as you know fertilizer is very hard on steel and they say it works the best of any product they have tried.

I have used a Permatex brand "rust converter" It seems to work ok, however, I did not trust it for painting, left it on there awhile, it actually does get rid of most of the rust, but then I buffed it off before applying paint. It did not bond well. I left it on all undersides, though.
We have used similar stuff on dairy skid-steers that come through our shop. A dairy is a very corrosive place, but it works well in this application.

I just recently coated my entire frame with this stuff called "rust-mort." I let it dry for 24 hours and hosed the excess off (like the instructions said) and what was left was this grayish, blackish color. I immediately undercoated it with 3m undercoat so I have yet to see how well it holds, but so far it seems ok. It wasn't too expensive, either.
By the way it was the kind you brush on, and that was a pain--literally! I wasn't thinking when it warned about skin contact. I just wore some chemical gloves, but my arms and face were bare. Ouch! That stuff burns...
