I've got a burton clash that is 11 months old and the base is starting to separate I think.They die cut Burton in white into the base and it is starting to swell at the seams and it looks like water is getting in and separating the base layer. All the edges around the cut areas are turning milky looking sort of. I will try to get a pic. soon
If it was purchased new from a authorized dealer then send it in before the warranty expires.
"Milky" sounds like classic base delamination.
