Too soon to tell how well it will last, since I just put it on in early November. All I can say is, so far so good. I'm not worried about it peeling, but it is vinyl and can be cut or scratched (so can paint or plastidip, for that matter)
If it lasts a reasonable amount of time, then I wouldn't mind reapplying it again. The vinyl was pretty cheap through Amazon at about $14 for a 12 inch by 5 foot sheet - that's a lot of door handles
It is very easy to remove if you change your mind or want to try a different color. Just use a heat gun or hairdryer, find an edge and start peeling.
