Where can I buy black appliance paint that I can brush on ?

Any hardware or home improvement center. You want "appliance" paint.

Check with Homedepot or Lowe's and they should be able to help you.

Try Home Depot or Lowes or a local hardware store to see if they carry Appliance paint. If you can't find it, you can search online to find where you can get it. I know Rustoleum carries one. Wishing you the best.

Some of these retails only catty touch up paint.Your best bet if you cannot locate it is Amazon

You can get the paint you need at most home improvement stores. If you are not sure or cannot find it, ask the manager of the paint department. I am sure they will have what you need to paint your appliance.

I painted a white refrigerator white and it turn out great. After a thorough cleaning I treated the rust, then touched up the rust spots with a tiny bottle of appliance paint. I used a couple of touch-up coats, sanding in between until all of the rusted spots were smooth and even. I removed the handles and logo, primed with oil based primer and painted with oil based Rustoleum. All of the painting was done with a foam roller. For the handles I used spray paint speciffically for plastic. My sister thought it was a new appliance.
