My mother had her plastic bumper replaced by a well known body shop and the paint started peeling within 6 months. My daughter had her plastic bumper replaced by a different body shop that did an excellent job of matching of matching what I considerd to be a difficult color to match and again the paint has started peeling within 6 months. Now it's my turn, I need to have a plastic bumper replaced in another difficult to match color (pearl white). If I go to the shop that's approved and backed by my insurance carrier, how can I be sure the paint won't peel also, or this is just to be expected?
