I remember your discussion about the Behr product Denny - maybe you could get the Klean-Strip up to 85% by evaporating out some of the water? of course then you'd need to buy twice as much wink

not clear why you'd use phosphoric acid, meant to be used as a wash, for a soak rather than using electrolysis to remove rust, which is way cheap and works so well

what I've been using now for phosphoric acid because it's readily available locally, is Metal Ready from POR15, intended to be used as a wipe and etch, but I've used Ospho with no subsequent paint problems - and either product after the electrolytic process
