We have had numerous customers paint them. You will want to remove the drivers and take the housings to a paint and body shop. Have them scuffed up or light sand to prep. Automotive paint in 2 step, base and clear. Just tell them to use very low temp for the cure. The housings are an abs composite. Which is what many car parts are made out of. So any good body shop will be able to paint them no problems.
This is how we paint them at our factory for the white and black. We only offer those colors becuase there are so many boat colors, it is better to have the customer color match them on their end. So we recomended it and tell people all the time to get them painted. I have seen, red, orange, blue, green, purple, flames,
There is a blue 3-Some in the misc gallery, a red 3-Some in the Mastercraft gallery, a pair of 485 in red in the moomba gallery, and a set of tribal flames in the malibu gallery.
