Does coloring the edges of CD's help the sonics?

I tried the Greenlite pen on a few cd's that I thought sounded brittle. Mapleshade's Afterglow was one of them.
It sounded better to me with the edges painted green. I problable will get another copy of it to make a better compairison.
I do not as rule apply it to my cd's.
I like to tweak and it did not cost that much.
Give it a try, I'm not sure if they still make it.
