A wrap with decent foil will last 5 years or so. Obviously it depends on climate and wear and tear, but after five years I’d personally peel it off and replace. I’ve battled an 8 year old wrap with cracked and dried out wrapping, and it was absolutely hell on earth. If I’d had a grain more of anger in me, I’d have told the retarded salesman, who promised the buyer we’d remove the wrap (against bossman’s instructions) that he’d have the pleasure of doing it himself. But no, I decided to be nice and do it for him.

Never, ever again.
