I normally don't post or look on here much as I'm a long time Mopar only drag racer,not a restorer or show car guy. I have 1965 dart 270 that is being made into a drag car with a full cage. I need to know what chemicals, brand and name type please, that would be best to remove surface rust and what chemical or paint type to use after getting rid of the rust to prevent it coming back or causing problems with the paint in the future ![help help](/ubbthreads/images/graemlins/custom/smilie_help.gif) Thanks in advance ![bow bow](/ubbthreads/images/graemlins/custom/bow.gif) Cab

Rust Cure, a phosphoric acid. See this video of it used on steel that's not severely rusted or pitted. The video is 8 minutes, but you can skip much of it to see the results. https://www.youtube.com/watch?v=hdtOrMURQK4Seven months ago I applied Rust Cure to just the right lower corner of a chimney hat on top of my roof. No scrubbing - just brushed on one coat. Second photo is a close up taken at the same time.

Today, 7 months later, I was back up on the roof and took 2 more photos in slightly different lighting.
Over the last few days I have chemically stripped paint off several small parts such as the hood striker, yoke cross member bracket, hood lock support, trunk hinges, and trunk torsion rods. After paint stripping, I sand with 220, apply Rust Cure, let it dry an hour, then reapply a few times until the steel is darkened. Just before painting I will reapply Rust Cure and wipe off. I'm expecting painting to be several months away and no rusting whatsoever on the stripped and sanded parts. Painting will be done directly on the wiped off Rust Cure.
An etching primer is a primer that contains phosphoric acid. Rust Cure is phosphoric acid. So is Rust Mort. As far as I know Rust Cure is the most acidic of any phosphoric acids I've used.

Thanks to both of you ![up up](/ubbthreads/images/graemlins/custom/thumbs_up.gif) I have a small bottle of the Rust Mort that I used last year on some small parts. I'll get a bigger bottle and use that on my K member and other parts along with a good paint primer ![up up](/ubbthreads/images/graemlins/custom/thumbs_up.gif) Thanks again. Cab
