Hi people,

Just wandering if anyone can help me to solve this problem,
If you live in melbourne you'll probably may have seen a blue golf with its roof discolouring into a fady blue -> white colour. When it rains or when i wash my car reverts back to its nice blue colour again....Why does this happen?

How do i fix this problem? and how much will it cost? It's really bugging me because it really looks ugly and embarrassing. thanks for any input
