For what its worth, I have tried several different rust converters, and the Eastwoods product (the 2 part converter - I have not tried the spray can stuff) worked just as good as the other stuff I have tried.
The converter only works on the top most layer of rust, so you still have to do all the prep. Scale has to be removed, and I still wire wheel most of the badness away before I gop on the converter.
But, these are the steps you would have to do with any converter, if you expected it to work well. Any pockets of rust not hit by the converter will continue to rust under the converter.

prep is important, that was not the issue, the converter remains corrosive when it is exposed to any moisture. if you could top coat it right away with a sealer it should be fine, howver that is impossible becuae you have to allow drying time, the humidity in the air is enough to start rust on what formaly was clean metal (trust me I did plenty of tests once I found failure, this shit actaully promotes corrosion of otherwise clean rust free metal.
if it is humid enough before top coat, the top coat will blister as the converter cuases rust. if the top coat is chipped, exposing the converter, the converter will rapidly take on water from the air and promote deep pitting corrosion. this is highly accelerated by the converter verses side by side test of untreated metal.
the bottom line is eastwood had to re-formulate this shit (still dont trust it) they acknowledgeed they had many customer complaints (do some internet research on car club and find out what happened to others) yet they continued to sell this shit until there stock was depleted, they even put it on sale price to get rid of it (they should have destroyed it)
they knew they had a probelms for over a year. very simple back ward tests proved that this shit promotes corrosion, no matter what kind of prep you do, even on un-rusted metal.
this system cannot work, one chip in t he top coat and you have accelerated rusting, humid day when you apply, or you wait too long (note the fast top coat time they recommend, your racing aginst rust forming, dont top coat and in a couple day it turns very rusty) with top coat and you have rust under your top coat eating away.
I have done lots of coating tests in my profession, this eastwood paint is pure shitty junk, it will promote corrosion, it appera to be about as corrosive as sea water.
it may look nice and shinny on top, but it is a disaster underneith it.
once bit, twice shy, stay away from cheapo junk paint like eastwood, instead get it from a company that know paint and tests paint, not some discount house that re-lables someone elses low bid junk paint.
fuck eastwood!
