It's a lot of work. But interesting. First you have to get all the strings out of the way, and then you should lightly sand the area to be painted. And then you should mask off what you do not want to be sprayed. And then you have to pick the right paint. Generally, as I understand it, any epoxy paint will do. Spray painting is an art. You don't want runs or sags. If you pursue this project, I'd be really interested in reportage.
