I posted a reply to another thread before finding this one, but my question is this: is this glass separating, or is it the ultraviolet light from the sun discoloring the plastic laminate? Why would the glass separate? I've never seen this on any other car except Mercedes. I'm not going to invest in a new window that will just repeat the flaw again. Could I inject something into the corners, like the stuff they use to fix chips, if the problem is separation? If it's light-related, can the process be reversed?
