I think you can paint the furai. I liked the colour of mine, so I left it, so I'm not 100% sure. But I think it does let you.
IMHO, you have to be careful with the silver chrome paint. I've seen pics in the photomode section of the forum, and
some silver chrome painted cars look hideous IMO. Haha. Course, it could be the angle of the photos, depending on the lighting, and maybe I'm judging too harshly. I've never gotten silver chrome yet, so I haven't used it on any cars myself. I'm merely going by pictures I've seen of other people's cars. And it could have to do with individual taste, of course. After all some people like matte brown I guess.
