I sanded down the cabinet and the t-molding edges, used "Goo Gone" to get any little pieces of glue left over from the original decals, hit it with some 91% isoproyl, and then used a tack cloth to get any remaining bits of dust. This is my first time using tack cloth and I'm in love... I'll never do another project without it. All edges got the glossy-black-Sharpie-paint-pen treatment.
THANK YOU to my wife. I could not have applied the cabinet decals without her. They're each 37"x74". That is a huge, very expensive, hard-to-work-with sheet of amazingness that I would have TOTALLY screwed up if she hadn't been there to help. We put the cabinet down on its side, my wife stood on a stool holding up the artwork, and we slowly rolled the backing a couple inches at a time. Slowly, we worked out the air bubbles and managed to get a pretty incredible end-result. A few times there was the smallest speck of dust that would get caught - we would just pull up the artwork, pick it off with a razor blade, and re-apply. The material itself was extremely easy to work with, on the other hand, the size of the print was not. Another thank you to
Lucian045 for helping me out with the printing process.
So here she is!!!
