I'm no pro painter but for what it's worth here goes: Here in CA. you can't get the acrylic enamel due to EPA crap. I used it with hardner and it worked well on the small stuff it did like a Kawasaki frame and a winch mount. Today the replacement is acrilyic urethane w/hardner and thinner. It's not expensive and it used it on the hood of my commute car over clearcoat/basecoat after I sanded it with #400. It has some orange peel but is OK. I did it outside and didn't expect a perfect job but it protects and I could work on it more to get it better but on a 89 Sentra with 383,000 miles it's fine. Now, if you want to paint a good job and it's real easy to work with but costs $$$$$$$$$$$$$$ is Dupont basecoat/clearcoat Chromabase. I have a 1970 Olds 442 showcar that was painted at the prison where I work (this was a project like they do at Harrahs in Las Vegas)and the paint is great!!! The car is a 95+ point showcar and Chromabase is fantastic. I did all the final detailing like painting the rims and some touch up work after the car came home. Chromabase is easy to work with. Hope this helps.
