The Logitech G logo on my G603 has been fading away.

When I bought it: It's a bright and somewhat reflective silver.

2 months later (today):

I tried to fix it with a silver Sharpie a couple of weeks ago.  It only worked for a day before my stupid sweaty palm started to smear it away.  The Sharpie was gone without a trace by sometime last week.

Don't worry, I have a better solution now...
