During the 5 years I've been dealving out CD's to potential clients and friends, I have never had a single label come loose, at least not one that I know of. I've never had one off center, and lately I've been able to pick up glossy labels at BJ's Wholesale Club at a very good price. Unfortunately, they've been out of stock for the past few weeks, and when they get more I'm gonna' buy a case of them. The quality is as good as it gets, and a light coat of protective spray eliminates any possibility of smearing. As for the thickness of the protective spray, it's microscopically thin, not enough to jam anything, and it's acrylic laquer, which you would have to apply a blow-torch to melt. It never gets gummy, but it can get brittle if too much is sprayed on the label.

Cheers,

Gary
