If you have to iron Monokote on Monokote, TURN THE HEAT UP HIGH!!! A guy in another forum gave me that advice and it works. You just have to put up with a few minor bubbles. You can always take a needle and pop the small bubble and iron it down quickly.
Good luck.
I don't like any bubbles. Windex, then squeegee the bubbles out, LOW heat around the edges, then brush (yes, brush) a light coat of clear Lusterkote around the edges. Works everytime, nothing lifts later. Been doing this for years.
