Monokote Blues
I have had problems with a couple of rolls of the shinny stuff.
When I looked at the side that is supposed to have the sicky stuff on it it appeared not to be there. The back side will have a little dull appearance due to the adhesive. Looking at it at an angle under the light you can tell if there is adhesive on it. Take the iron and put it on the backside ( adhesive ) side and you will know for sure. I tossed mine into the dumper since I had cut it to size and screwed up a wing. Next time I check first before cutting.
