I found about eight older plastic toy cars for ten cents each at a yard sale. They are not really any scale, but they are close enough for 28mm. While not very detailed, nor any particular real world design, I figured they would make decent empty husks of cars, useful for cover and not much else.
To try out the painting method, I am just going to do one car, the others will follow (and show up on battlefields!) as I get a chance to get them done.

|A salty snack!|
Watch your eyes - the topcoat is next!
|Yellow over the salt and rust|
After the topcoat was dry (I left it alone for 24 hours or so) I dunked the body in warm water. I found out it was actually buoyant, so I switched from a tray to a drinking glass (disposable) so I could keep it submerged. I used a pretty nasty old brush to knock off the salt as the water worked to dissolve the salt. I didn't realize how much of a mess it would be, but luckily it was mostly water that made it a mess.
If you try this, be aggressive when you knock loose the salt, BUT, be careful as you can scratch right through the base coat rust color if you are to heavy. I had a few spots that I went all the way through, but I figured I could cover those up easily enough.

|Some touch ups but it looks pretty rusty|
Overall, I was pretty happy with the result. The car is still too good looking for a rusty hulk, so I add a black and brown wash (very similar to my zombie wash) to dull the paint and bring out details.
|The wash darkened it a touch|
In the end, this is a decent effect, and I like it. I am going to try it on the remaining cars I have, I will go a bit heavier on some of them, or at least in certain areas much heavier. My goal is just some rusty looking wreckage, which this definitely looks like.
In comparison, I have the new wreck next to the VW bug wreck I did recently. The bug is paint over the existing paint job, not the salt method. They both look like wrecks, just different.
This method does not save any time for rust effects. It does give some pretty interesting paint effects, as the paint is really peeling away from the model, it gives a feel of rust showing through. I think it is better used on models that are more 'active' such as tanks and cars that still in use. I could see applying the salt and then a finished coat, then using the salt to reveal rust, that would be a very cool and dramatic look. If I can dig out a model to try it on I'll post some pics of what I mean.
