In your instance I suggest 1 of 2 things:

1. Due to the size of the trim piece, use Monokote and apply it using the windex method. AFTER IT HAS DRIED (24 -48 hours) iron all your edges with a trim iron or seal them with clear nail polish.

2. Use the Ultracote, but start in the middle of the trim piece and iron towards the edges. Keep tension on the piece while ironing. You should be able to attach it with few (if any) bubbles. Any bubbles you may get, ***** them with a pin and iron the bubble towards the pinhole to get rid of the trapped air.

The woodpecker is not necessary, especially over open areas.
