Have a job I'd like to finish but the painter hasn't finished the in-wall and ceiling speakers for me yet. Thought of buying a $4-500 sprayer and make it a service I offer (after some practice!) but thought I'd get feedback.

The painters I have seen do a great job water the paint down and spray a few very light coats. However, I've read of others who claim excellent results by "dry brushing" - essentially getting almost all the paint out of the brush and then going at the speaker.

Your comments on spraying vs. dry brushing are appreciated.

Then, what about charges? Not much setup for a brush, but with a sprayer, you'd set up, spray, then have clean up. Charge per set or per speaker? One flat rate?
