Non-mechanical stainless to stainless?

[jtiii]

I need to mount an ~12" wide cut stainless script word to the outside of a commercial dishwasher. I need to mount it to the door and unfortunately when it slides open it slides in front of the wall of the unit with very little clearance between panels. The wash water is 170 degrees so the outside of the door gets quite hot. How should I fasten it?

3m 467MP, it's the same stuff they likely mounted the badging with, rated long term temp exposure of 300F, short term of 400F, 2 mils thick.
