Probably cheaper to have a painter come into the house and paint it. Where I work we have a spray shop and I would consider it an expensive way to paint, most of the work is in the preparation of the item for spraying, everything is so well fininshed that it almost looks like plastic.
Good point, I assumed spraypaint would be the best job,never thought of it looking like plastic...might even consider painting it myself..alot of work involved but there is no deadlines.
