Gary,

Including Kevin's bus, I know personally of 5 buses that have experienced the problem with the skin...

And, since I own an XL, I haven't really even been paying close attention to this issue.

To quote one of the tech's "we've done so many we can do them in our sleep".

So, it would appear that the problem extends beyond a hand full of coaches.

My concern would be that the problem does not appear to be the result of a certain batch of adhesive, but rather that they're changing to a different adhesive altogether.
