However, you need to be aware that there are TWO 3M 600 tapes, one from
their stationary division which has a lower adhesive force and one from
their industrial packaging division, which has a much higher adhesive force.

So, if you want the mask and lettering to fail, you use the industrial
tape.  If you want it to pass, use the stationary division tape.

Humor only partially in-cheek.
