I thought I answered this before, I have a bad habit of writing what I want to say and then hitting the Back button DOH!

What I tried to say was my best luck (and I'm no covering genius) has been with sticky-back covering like Ultra trim or Monokote trim sheets used with windex and little or no heat.

Spray on plenty of windex, this keeps the stuff from sticking while you want to move it around into position.

Keep squeezing the water out as it dries with a squeegee, when it's dry completely (allow 24 hours) it will be stuck down hard. You can go around the edges with an iron on low heat but should not need to.
