I'm assuming you're using the new (clear version) of AI. There was a thread recently on Audioasylum about the new version "clouding up" some CD's. I've used both the old (blue version) and new and did experience some clouding on some discs, although I have never had a disc skip. I think that you need to apply the new version very sparingly (a little goes a long way) and make sure that it is very dry before you buff it off. If you've got cloudy discs or are experiencing the skipping, I'd suggest totally removing the AI (and the marker) using one of the AI cloths and some isopropyl alcohol, then rinsing with tap water. I would then reapply the AI (frankly I'd skip markering the edges-I no longer do that). If you have further problems, I'd contact Audience personally and post back what they have to say. I am still using the AI (I like what it does) and have had no problems.
