Black 3M Double Stick
I use this stuff all the time at my work. I cost a little bit more, but it really works. The real perk is that the foam and the glue keeps its elasticity for much longer. The white stuff tends to stiffen and decay alarmingly quick. It doesn't cost too much more, but it is worth it. Be carefull though, if you buy a big enough roll you will find yourself sticking all kind of things all over the place. The good thing is, since it doesn't turn brittle so quick, it is easy to change your mind when you decide you really don't want to look at a the plaque with the once witty phrase every time you sit down for dinner, then you can simply pry it off.
