I used to use glue - now I am all tape - 3-mil up front. Other Walker tapes around the perimeter. I couldn't agree more with the 3-MIL hairline.
Jorn and chazisland if you put a stronger tape behind the 3-mil on the hairline there is NO LIFTING and it is easy to clean as there is only 3mil tape on the front 3/4 inch (touching the piece).
