maybe someone out there remembers forum about stripping old paint off parts and also removing rust? I remember it was some sort of acid that could be purchased at home depot. thanks for help

Phosphoric acid, also known as "Naval Jelley." Just don't put any into your Navel.

Q

Man, that's gonna hurt!

I use this stuff called Rusteco. Its not acid, so it doesnt harm the metal. It is also non toxic so you can get it on your hands. It has been working pretty darn well for me. Check www.rusteco.com

The naval jelly (or at least the jelly that is close) that I have seems to be lipid based.

Thanks for the advise ill try anything

If the parts are small, there's also a way to do it electrolyitcally with a plastic bucket, some washing soda, a small sheet of stainless steel and a battery charger...

Q

Just don't use naval jelly on aluminum. I tryed cleaning up a timing cover a while back with it and it ate the cover up.

I tried to crack a funny on my last post there. Too vague again? Scott, help me out here!

Maybe you meant to write "Navel" jelley? Or did you mean close to the navel?



Q

Yes! Thanks, Q! I meant to infer the "navel" spelling, and that's what I meant about being too vague, I should have just used "navel". And just to finish off what I thought would be a clever retort, lipids are, basically, what our bodies store energy in: Fat! So I was referring to what us Norwegians would call a "yelly belly"!
I'll try to take it back a notch or two.

TOHCan, you seem like a smart guy. I have to admit you were the only guy who recognized that I misspelled "ignorance." However, I am pretty sure you meant to imply, so that we'd all infer ... not the other way around. Check out a Dennis Quaid movie called "DOA."

And here I was thinking you meant the lipid based oils that do not dissolve in water, such as, perhaps, Vasoline ... (though I admit I think that one is in fact petroleum based and not lipid based. But, what do I know? I'm not a biochemist.)

Q

Oops! Got me on that one! I sit corrected! Oh, the implications! I guess I should leave the inferences to others from now on. And I'll admit, the biochem stuff is mostly Greek to me!

Has any one ever herd of using cristal draino for removing paint from small parts? I saw it in a collectors mag. on refinishing cars.
