Chasing rust in the tub (Continued 1) (1 Viewer)

I haven't been able to go get any dry ice to remove the deadening yet, so I figured while i wait for the weekend I might as see how well the rust converter works on what's currently exposed. Honestly, I'm a little underwhelmed, it just seems like it didn't do that great of a job. I hit it with the wire brush to remove the loose chunky scale and left surface rust for the converter to act on. Applied, waited 15min and applied a second coat, this is how it looks ~24 hours later.

Is this the desired effect; I've never any of this stuff so I'm not sure what to expect. It all certainly seems to have changed some, but i still see brown underneath the sheen--is that normal?

Yeah, it's not what you'd call impressive but it often works. Stops the rust from growing anyway. I applied it years ago to rust spots where the plastic clips into the body at the door sills and it so far has held.

In a case like yours I would be skeptical too.

evapo-rust really truly works but i dunno how you'd apply it to something like this. I mean they recommend a shop towel soaked in it and covered with plastic but it would take days to weeks and numerous applications. It also might be LA's Awesome All Purpose Cleaner from the dollar store spiked with tannin from the homebrew store (based on rumor and research - i need to test this theory).

Boaters often use ospho or jasco rust converter along with some rubber gloves and some red abrasive pads to scrub rust away. These are phosphoric acid based products - not like the milky white stuff you brush on. If you don't want the 'prep' layer you can rinse it off with water before it cures.

@AUGuy Hit the Harris Teeter nearest you. They all have a dry ice cooler somewhere near the front. Ask at the customer service counter since they keep it locked.

Thanks John! Been wondering where I'd find some.
