acid dipping rust removal

I m gonna share this cause i don t want anyone to get the nasty feeling in their gut like i did from using muriatic acid. I read once something along these lines and decided to try it. We had a 37 pickup cab fresh from the media blaster, but still had a small amount of rust in a few deep pits. I tried it on a small area. BOOM!!!! It was gone. I neutralized it. All seemed well. So i did a lot more. Neutralized again with baking soda and water. Let it dry..it flash rusted a little bit, but the next morning i planned on d.a.ing all the metal down and epoxy priming.
Came in the next day....whole cab flash rusted......WTF???? So i d.a. Sand anyway. By the time i get around the cab. Its already lightly starting to flash again. WTF???. NASTY GUT FEELING
So....i talked to a friend of mine who owns a powerwash company. He sold me a product called "RUST-BAN"... Acid washed the cab. Rinsed, soda washed, rinsed again, and while it s still wet sprayed rustban solution on it liberally. Let it dry and it was fine. Scary time tho. I m sure there are other cures, but this stuff saved my butt.

When you first use it you re think holycrap this is awesome, but it can bite you.
What i didn t realize was the shear potentcy of the acid fumes. That **** is nasty and can be trcky to work with. I learned to never use it inside either. Fumes alone can flash rust every thing metal in your shop thats not coated

If you leave steel in it too long it will tear it up. I ve left bolts in too long and they look crazy when they come out. Almost like the inside of a bone in the edges.

ON THE PLUS SIDE... It works fast and is very helpful. I still use it now. I m just careful
Long story but i hope this helps
