an alternative to tape might be removable vinyl.
I used to have to make a lot of signs at my last employer many of which were price tags on used equipment.
We used Oracle 651 if we wanted the sign to stay (company logo) and oracle 631 if we wanted to be able to remove it with out heat.
Both of these would stay on aluminum, steel or paint even in sub zero temps.
The nicest thing about it is that it can be bought in rolls up to 36 inches wide and it will not hurt your paint.
Regular vinyl safety tape.
Oracle 651 scraps that I had sitting around.
I had to piece a lot of tape together for the yellow and black stripe piece. The solid red and the adjacent black section were both sign vinyl.
