The hardener is available at Tractor Supply. In lieu of the "expensive" frame paint try Chassis Saver from Magnet Paints. About half the cost of the other guys and it works real well.

You can also buy gallon jugs of "Prep-Sol" at most paint suppliers to clean any surface you are painting. I use a spray bottle to apply it and then wipe it with a clean rag.

i use pressure washer to clean rust flake off, then ospho to treat metal, then give it one or two coats of rustoleum red oxide primer cut 40% with acetone.

then paint with rustoleum industrial paint cut the same 40% acetone for frames. i have not used the hardener in the paint yet, i plan on doing that on the 88 F-SuperDuty when i finish the restoration this summer.

similar to what you do but I use KleenStrip http://www.homedepot.com/p/Klean-Strip-1-gal-Phosphoric-Prep-and-Etch-GKPA30220/100406369 after that dries I rinse off any of the white residue and spray and rub down with paint thinner. Then do the primer than paint. Seems to last and hold up fine. Supposedly this is recommend but I have never used it in place of the prep and etch. It is made by the same folks.
