Can the metal plate be easily removed? Just wondering since I don't necessarily trust the adhesive on a lot of those adhesive foam/felt materials. A lot of the time you'll end up transferring the residue and making quite a big mess. Not a problem if the plate can be removed and cleaned. Hurray for ultra sonic cleaners.

As far as Creatology sticky felt goes, it withstood the rather rigorous action doing the rounding/smoothing that jerg described (I did it more than a dozen times for each gap; 20-30 passes, I'd say).  I didn't use my fingernail, but the smooth, rounded end of a small USB stick.  None of the felt came unstuck in the least.

Does the Creatology sticky felt leave residue when removing?

Does the Creatology sticky felt leave residue when removing?

My guess is most likely.

One trick I use is to stick the Creatology foam on my shirt and peel it off about four or five times. It makes the adhesive less effective.

Na, that takes about 7-8 successive stick and peels. 4 is about right for clean metal surfaces. 3 isn't quite enough.
