Quoted from KeithinMI:I would concur in that a wrap of 5mil mylar will solve that problem. Alternatively, and probably not as durable, a thin coat of clearcoat over the decal would protect it as well.
Concur, don't own a TWD but do a Shrek (orig owner) and my "beer can" looks brand new - sure doesn't look like the pic above as I wrapped bottom 3/4" or so in mylar.
Therefore assume mylar should be your (or Stern's - during production) answer...
