Pre-cut DIY PPF kits vs professional install
A $50–$300 pre-cut kit can work on flat panels. On bumpers and mirrors it usually ends in visible edges, trapped dirt, or lifted corners.
Where DIY works
Door cups, door edges, the rear bumper ledge, and headlights on some cars. Small, flat, low-curvature surfaces.
Where it fails
Front bumpers with complex curves, mirrors, and anything that needs stretch. Film that is not stretched properly lifts at the edges within months.
The middle path
Many shops will install a customer-supplied pre-cut kit for a labour fee. That gets you a professional hand on the hard parts without paying for film twice.
