Not personally, however, I admit some camera's look brilliant with a different paint job.
It probably isn't something everyone will be looking to do, especially with a camera of high value (?), although if you aren't looking to flip it or make $$$ out of it - why not?
I'm seriously considering having one of the small Rollei 35's painted - I just need to figure out which model I'd like to do this to. I have the colour chosen, and while it definitely won't be to everyone's taste, it will be something I enjoy using and that is the #1 thing, IMHO.
