I finally put the last coat of black paint on the faux windows. I used Rustolium black lacquer to get a glossy finish. It’s not perfect but it’s better than it was and I’m happy with the results. I will probably put a couple of clear coats on in a couple weeks when I feel like masking it all down again. The pictures show what it looked like when I started and the finished product. The white on the finished windows is reflection off the shine.
