Then sprayed on a coat of primer.
Then I used the chrome spray paint that I used on the bathroom light fixtures. I also sprayed on a coat of clear to keep the chrome faux finish intact (something I wish I had done on the lights).
Here's how it looks finished and in use, I ended up not using it under the sink but in the breezeway to hold our supply of paper bags. Remember when you're spray painting do it in a well ventilated area and not near you're car!
