I brushed a little along a vertical panel and it ran down just like a real oil leak, which is exactly the look I wanted. The brightness is strong enough that a thin line still reads clearly once it dries.

This stain brown goes on bright and thin, so dragging it down a panel actually looks like rust weeping down the surface. I used it over a chipped bumper and the running streaks settled in exactly where I wanted. Took a little layering to build up the deeper rust tones, but the effect is worth it.

The brown is brighter than I expected, almost orange in some light, so I had to tone it down with a darker wash. It does run nicely when you drag it downward to fake a drip stain, though the effect is pretty subtle unless you layer it. Fine for rust streaks, just not the rich dark brown I was hoping
