Cleaning rust pits / road rash from paint
 

I am working on the 68 Camaro I just bought back. The bottom of the car is most all original paint (this is an LA car). I am guessing where the rust accumulation is where paint was very light if not non existent. As pictured, there is also road rash in spots that I'd like to improve on.

I have tried buffing compound with a couple of different pads and had a minor improvement. I feel it could be better.

These are a couple of pics where I have not touched anything....

Here is where I have been buffing....

I saw this video a while back and at the 5:19 mark, they speak of using an acid solution that naturalizes the rust in those pits. Has anyone does this and what is the magic brew?



Any other suggestions? I'm all ears.

In advance, thanks!

Wire wheel cleaner and a wet toothbrush.. like Eagle One brand or something similar.

What about NJ Steve's Evapo Rust Kiddy Pool (Basin) and Fish tank pump and sprinkler set up on the rear qtr?

I had given that some thought as well. When I saw that video, it really got my attention.

Muriatic acid. A great share of the top side of the '67 Chevelle Concours wagon I just finished was peppered with surface rust specks due to thin paint.

Apply to a small area, wait a few, neutralize with water and wipe off. follow with what ever buffing you want to do, then most important, a good wax, like Collinite 845.

Also, Dannystar used a system on the Butternut Yellow 68Z28 that was pimply and rusty, I do not remember what he used tho.

I have used muratic acid and then a solution of baking soda and water to neutralize the acid, followed by Meguires #7,

You could try citric acid first which is a good bit weaker.

Its hard to do but its best just to leave it as is,
your job now is to keep moisture away from the car
and the environment that the car is keep in dry.
Thats preservation.

He soaked rags in evaporust and let them sit on the rusty surfaces.
