Herb and I have put this stuff in his buses and in my bus as well. No pics, but it's not a hard installation. You can buy rolls of the stuff at Lowe's, depending on the width, I think the 24" is about 30 dollars.
First we cut the stuff to fit in the door or side panel. It's really easy to cut with your scissors. Then we used a spray adhesive to attach it. 3M makes a good automotive grade spray adhesive that won't yellow or deteriorate in the weather. It holds pretty strong. You'll get glue all over your hands, but if you're patient you can line an entire bus in about a day. I think the results are well worth it.
