I agree with another poster that heating with a blow dryer carefully and working slowly will work best. It can be a slow process. Question. Why bother? If the camera works fine and you are using it I wouldn't worry about appearance. If you want to improve the looks to market the camera you may consider the fact that a used car is worth more with faded paint (the origional factory paint) than one that has been repainted. Just my 2 cents worth of probably useless feedback. HAHA!
I see a lot of input of using acetone for various needs but you need to be very carefull with it. If the camera has plastic top and bottom covers acetone will ruin them.
