I use the craft paint from HL or Michaels. Any of their brands seem to be ok. The airbrush that I use from Harbor Freight is dual action. I bought the kit that came with the airbrush and compressor. I think the Windsheild Washer fluid has helped me get the paint thin enough. It takes many coats to cover with as this as I make it, but the result is oretty good once finished.
