Anyone here tried weathering with a vinegar rust solution?
I recently used vinegar to remove heavy rust on a couple rusty railroad spikes. I sifted it for chunks and the leftover result was a neat heavy orange rust solution. I'm wondering if it would be worth trying to weather railcars with this liquid. I seem to remember seeing something in the past about weathering with "real rust" but I can't seem to find it.
I'll probably give it a go on a cheap car anyway, but I thought I'd ask here first.
If vinegar is safe to use on trains, it seems very promising since vinegar has a fairly low surface tension, is cheap and rusty railroad spikes are easy to come by here.
Lastly, if vinegar left to dry is going to be harmful to paint/plastic/etc, perhaps first neutralizing the solution with slow application of baking soda to get a neutral mostly-water rust solution?
