You can buy the duracoat kit and do it yourself.... I know I did mine a long time ago with an airbrush gun. Duracoated my LCP, 2 PF9's, my M&P15, and AK, it's been ~5 years and still looks good to me
I don't have access to an airbrush rig and I've contemplated using the aerosol method. Do you have some pictures you could share with me?
