I've decided to use grocery store variety cling wrap and gently heat it to shrink it. A couple of tests tells me it'll work just fine. My only concern is longevity. For example, what will it look like in 5 or 10 or 20 years? Hopefully not a pile of old dried out crumbly plastic shards. The product I'm using is LDPE (low density polyethylene), according to the product box. I couldn't find information about how it ages.
