I just wanted to use it as a stencil, just like in my previous post when I first attempted contact paper.
I cut it along the lines, as perfectly as I could.
Then carefully applied it to the sanded, primed and white-painted box.
I tried to align the stripes about an inch apart all the way across.
Next, I again, just sprayed over it with gray spray paint (I wanted a gray box, with white chevron stripes) and let it dry.
the moment of truth: this time, when I peeled off the contact paper, there was a little bit of seepage…only a small amount. and actually, I was able to carefully scrape away the gray paint with my fingernail on some of the spots that were obnoxious to me.
I finished it off with a top coat…and reassembled the box…
