I found an antique mirror in Birmingham Alabama that had great lines, but a very boring white paint finish.
Using one can of Rustoleum spray paint in Lagoon Blue and one can of clear lacquer finish, I was able to refinish the mirror to a more modern look.
I used painters tape and newspaper to protect the mirror area, then used thin layers of the blue paint to build and evenly cover the mirror.
Its easy to think that when using spray paint, you can rush through the job. But being patient and using thin layers, ensures you use only enough paint to cover and avoid drips.
