As I looked out of the window at work this morning I noticed that one of our window surrounds looked darker than the others. Immediately thinking of this post I had a closer look and sure enough we have a leaking window and the darker ledge was covered in water. Well done AB!

Now if you can just suggest a way to get the rain to stop so we can get the window fixed I'd be doubly grateful!!

why is it that paint is lighter when wet and darker after it dries?
