I finally got this one to work and I think I figured out the problem. This enclosure is bare metal that I polished. I used A type paper.
So, I tried this 3 times today, first two had the same problems I experienced earlier (incomplete graphic transfer). The trick to getting this to work was to dry the label before applying it to the enclosure (glue applied). It dawned on me that the water left on the film might be mixing with the glue and creating areas without bonding. After applying the dried film, when I used the hairdryer there was very minimal bubbling under the film, pretty much only around the drilled holes. The first two had a lot of bubbling everywhere, even though I smoothed it very flat when I first applied the label. Considering, this is my 5th try at this graphic, I think I'm on to something here. Also, I didn't note it, but I seem to recall drying the label for the bat enclosure that worked well.
Total procedure:
1. Put label in warm DI water
2. Apply glue to enclosure
3. Remove label from water, and dab dry on a paper towel
4. Put label on enclosure and glide it into position
5. Smooth flat with piece of foam (squeegee)
6. Dry with hairdryer 10 minutes
7. Put in toaster oven at 250 F for 30 minutes
8. Remove film from label
9. Clean excess glue with isopropanol
I'm not sure if the toaster oven is necessary but that's what I did this time.
