Thanks for all this great info, Bill! This is a definite keeper as a reference.
BMF is a great product, and looks fantastic if it all gets put down snug. One thing I have used to help get the BMF to snug into tight spots is the eraser on a pencil. Just a normal, wooden, lead pencil eraser. It is soft enough to not harm the BMF, and firm enough to snug the BMF over small ridges, and into shallow grooves. I have also used a cotton swab to help burnish the BMF down over trim, and it also gives it a bit of a polish at the same time.
One thing to keep in mind is that BMF has a shelf life. If it isn't sticking well, perhaps the adhesive is too old. Keep BMF sheets out of sunlight, and store in a drawer, and in a large ziplock baggie to help extend it's life.
Hope this helps some!
