Yesterday we used the remaining Insulator to line the inside walls. We ran out just a few square feet shy of finishing. We also decided that having windows on the rear wall would be too difficult and costly to properly insulate. So we painted the inside of the windows with gray primer and covered the windows & wall with 2" of rigid insulation.
Using a heat gun, Rhonda also began removing the "School Bus" lettering from the front and rear exterior of the bus. I was able to remove the stop arm from the side of the bus (stop sign that swings out when kids are loading/unloading), as well as the cross arm (which swings out from the front bumper to prevent kidlets from crossing in front of the bus.)
