I've been using the Rubbermaid shelf liner for years. In the early days when DW and I were living in out '87 Toyota Dolphin, I used an office type Swingline stapler to tack down the liner. Now that I'm older and wiser, I use the more modern stable gun with the shorter of the available staples. They are easy to remove if a change is needed with the good old office staple remover.
