I have had a couple with Bodyguardz protection, a product very similar to Wrapsol, and none of them have had edges peel. However, some edges will catch lint on them after a while.
i have a wrapsol, no peeling or lint issues, one problem however is that my edges have a orange tint to them. i will be requesting a free replacement soon. must be where the oil collects or something.
In the palmrest area i get stuff caught around the edges. This is perfectly normal though, since my hands get sweaty and whatnot. The fix to this was taking a cloth (i use a microfiber) and wiping it down, works for me.
