Luck of the draw. I find that the black residual lines that stained tend to grab my eye and interestingly, I never even noticed the bright yellow sticker before reading the thread. Wish I hadn't read the thread.
I figure that it is ridiculous to buy new ones but I didn't price them and then I would probably get new stickers!
Anyway, it sounds like ~ 1 in 4 people are having trouble doing this, so my advice is to accept the yellow sticker. After this experience, the idea of other DIYs don't look so compelling to me.
