the best rustproofing and restoration products are made by POR-15. They have a website. This stuff looks new to me and might be good but por-15 has definitely stood the test of time. If you do try it, let us know how it goes!

 

I don't believe that POR-15 has a rust removal product, right? I'm sold on POR-15, but I want all of the rust gone first.

I've been considering blasting or acid dipping and the above looks like it might be a good alternative. I've got 2, possibly 3 280Z's that I'm restoring so the DIY methods are attractive: a one-time investment in equipment, use my sons as slave labor

Any experience with this stuff? Thoughts, comments?

 

Try that "Rust Preperation" stuff by Permatex. Sold at Pep Boys. It really works deep. NK

 

My guess is that it is an aqueous solution of oxalic acid, a weak organic acid that chelates iron (III) ions (from rust, Fe2O3), and some polyetherpolyol to disolve grease. You do not want to injest this stuff or get in in your eyes or get it in an open wound.
Whether you could formulate this yourself at a cheaper price is unclear to me.
Good Luck,
Joe

 

"....Inhibits rust from reforming for up to 4 weeks indoors." (???)

Am I reading this right?....what about outdoors and what happens after
5-weeks indoors? I'm a skeptic I guess, but then I believe you'll never
keep it away unless you garage it always and drive on dry days only.
....agreed w/ nrkrell abv:
The rust convertor by Permatex doesn't take the rust scale-y crap off
but is super if surface is ground down/dremel'ed/ or wire brushed to
bare metal as best possible first. If your prone to getting arrested, you'll be used to those black impregnated fingerprints it leaves (use gloves, I don't know what's in it, but stays on a LONG time!) I only have one black finger today, had to prep a vent window for the truck that mysteriously popped, shattered, (like a gun, really) going down the freeway...used a Dremel and just that, Permatex w/ a paintbrush tho' to confine to a couple of frame spots and then the entire tension spring after wirebrushing.
Permatex or other rust convertors at least act like a sealer which I don't
imagine this stuff does....unless maybe you intend on a different sealer after.

(at first, I looked at that..."BEFORE" (an axle) and "AFTER" (a diffy)....boy
that stuff really converts major parts too!

 

I'd try it & see. Also look into dealer pricing.

 

I'll bet the 4 weeks thing implies that it will protect without any other stuff. It looks like it cleans the rust up pretty well. I'll bet if you POR-15 it afterwards you'd be set.
