That's actually a rust remover not converter. Works great, I've used probably 20 gallons or so of it in the past 10-15 years. Let it do its work then run a wire brush over it while you rinse it of with water and it brings it down to bare steel. Only suggestion I have is due to the way your doing it you should probably see about soaking the paper towels at least once a day. After it starts working on the rust it slows down and eventually stops and turns black. A fresh dose of it and it'll start working again
Salt is bad out here too, does the same thing as you describe out there. The concrete where my wife parks is taking a beating from salt even. Sure wish people could drive decent enough where sanding and being careful would work! Now the city is claiming they have cut back on the salt due to salt pollution in Rapid Creek, but it sure isn't showing up. There's literally piles of salt in places after the snow has melted!Cat is living in some of the worst environment there is for rust. I just hate driving my vehicles into eastern Minnesota in the winter. Get back home and they look like they've been sugar coated there is so much salt on them. Wisconsin and upper Michigan are the only places I've been that are worse. I hope you can beat your rust problem. We put a man on the moon decades ago but can't build a vehicle that won't rust apart.
I have an 05 Escalade with 94,000 and so far it looks good underneath. The exception is the spare wheel which is badly rusted. I'm surprised that someone hasn't come up with a shallow in ground tank that we could drive through that contained a rust converter or neutralizer of some sort.
Didn't used to be that way until recently, NY is bad for rust, lower part of the cab on my f250 is coated with bed liner, underside and frame will be done this summer, I'm just gonna paint the top of the flat bed as I want to be able to slide stuff on the bed.PA is bad for road salt too, if you can find a ten year old vehicle here without rust I can pretty guarantee it never left the garage in the winter.
