How to Make Hardware Look "Rusty"

I've refinished a few projects that needed some good rusty hardware for the final touch.  After scouring the internet on how to do this, I gave up and came up with my own version.  It's much easier than anything I could find out there. 

So, here's what I started with.  I had painted them previously, but didn't like how they turned out. 

First I sprayed them with Rustoleum Multicolor Textured paint.

I let them dry for about 15 minutes.  I didn't want the paint to be completely set because I like to mess up the texture a little. 

Normally I use black, red, and orange paint but I was out of orange so I improvised.

Next,  dab some color onto your project in random spots.     

I wear gloves and just dab at the hardware with my fingers until all the colors are blended. I usually add a little more black as I'm going. There seriously isn't a science to it.  Just go to town blending.

Not the best picture, but here it is on a thrift store shelf I refinished.  It's a wedding gift that has a personal touch, but didn't break the bank!
