I have yet to be able to apply large strips of covering (Ultracoat) over covering without getting a lot of air bubbles, no matter how careful I am.

I am wondering if I can use the soapy water method to apply the strips of covering and then iron instead of just ironing on. I seem to have the most trouble when doing sthings like my last job. Applying some 4" wide by 2' trim strips over the base covering.
