How to accelerate "patina" (I want something to rust QUICKER!)
My 49 Dodge truck was missing one cab clearance light from atop the roof when I bought it, and the replacement that I found was in much better shape than the other two. I tried sandblasting the metal shell and then dropping it into a 5 gallon bucket of water, and even added some salt to the water to try to make it rust a little faster. It's got that orange-y colored slime on it now, but I need this thing to RUST more quickly. The rest of the truck is almost done, and I want to hit some events pretty soon. Any ideas??? Thanks!
Bleach will add some nice patina, not sure on rust but it will blacken the metal and fade paint, im sure it rusts it a little.
My girl has the formula down better than I, she is a master at rusting metal.....

It's the steps I may not have correct.
1. Hit it with the Acid, let it rest a bit
2. Hit it with the Salt water mixture, let it rest
3. Hit it with the Hydrogen Pyoxide and watch what happens....
But like I said, she has the process down, and I just would ask her..... so I don't remember where we used the Vingager
Here is a before...
And after ....
Wow! Rusty, please get us the exact directions if she has it down pat, there is no need to re-invent the wheel if you already got the blueprint! I need to get my patch panels around the bottom of my coupe rusted in soon so that I can clear the whole body and seal it.
Thanks in advance.
Okay, here is the order of the process.

3. Spray the metal with the vinegar, get a good coating, I think we did this step at least two maybe three times before step 4.
4. Rinse off the acid and spray on the sea salt water mix.
5. Spray the now salted surface with the hydrogen peroxide or a mix of the perioxide with a bit of vinegar. think an 8 to 1 mix, or 16oz of perioxide to 2 oz of vinegar.
It's really cool to watch the metal turn and foam while it rusts.
If it doesn't do much you didn't get the acid etch or degreased enough at the begining. If it does turn and you want more rust or color, don't hit it with the acid or vinegar that will just remove the rust you did.
Keep repeating steps 4 and 5 till you are happy with the looks.
In our case the only part I did clear was passenger seat but not the drivers, tunnel or anything else. I did get some rust rubbed off for a bit, but that hasn't been a problem for a long time since.
Here are some shots I forgot I had when we were doing the treatment to the interior.
Thanks Rusty! As soon as I get my air ride and interior sheetmetal finished I'm gonna do all my patches on the outside of the body.
Awesome, thank you! I LIKE your results!!!
Going to give it a try over the weekend!!!

I've had pretty good luck with a BBQ grill. My shiny zinc plated tailgate chains were black and installed within 15 minutes. I bet if you basted with one of those rust concoctions you could quickly have a rust finish.
