Snagged an old pop up frame. Lots of surface rust, nothing deep.


I remember all the sand, sand, sanding, grinding etc I did on the Sunhopper.
As I looked into alternatives to this masochistic endeavour, I came across Corroseal and thought, 'give it a shot'.
Well, I'm impressed....the stuff turns iron oxide into magnetite and the results are pretty darn good.


It doesn't work if the all the rust is removed. Just remove flaky or scaly rust, I then used a bit of sandpaper to get in crannies then blew it off and wiped with denatured alcohol. You paint a thick coat on...(it looks like Elmers glue) ..I used a brush, could use a roller, they don't advise spraying it or diluting and let dry 24 hr.

They say you can use primer over and paint (they recommend oil base). I'm going to spray Rustoleum I think.

I think this has great least it does...for me. :)

I've used rust converters on several projects before: Klean-Strip spray-on, Corroseal from a jug, and even Naval Jelly in a concentrate.

The spray-on was just used to take the red tinge off of my old '69 C-10's patina, converting it to a black and green combination (which I liked, and even waxed over it!), but for real rust conversion I used Corroseal (on automotive axles, frames, etc.). After removing scale, it converted the surfaces nicely, and usually looked good enough to not require any painting over (on beaters & daily drivers). It stopped the deterioration of my trailer's original axle, though it had resided in a marshy area for twenty years, and almost made it look OK (though badly pitted). It's a good rust-stopper.

I think the naval jelly was either too strong, or left on too long on an antique garage jack (front-end lift bumper jack from the '30's) I was trying to save, but after continually applying coat after coat of the jelly, it just fell apart. It was probably all-rust, and no substance anyway.

OSPHO(got it @ ACE) is another

a quick swipe w/ a wire brush and paint it on(greenish liquid turns black when cured) to become a "sound" base for painting the color of choice

began using the stuff for the battery box under the back seat of my VW Thing that had thru rust
