yeah, you are right.
I certainly think it would take more than 2 rolls to stick up a car because you'd have to wrap it right round the wall.

In fact the crucial bit would be getting it vertically supporting the main direction of load, and seeing as you can't wrap it under a wall then I doubt it'd work. The stuff may be strong, but it's not actually massively sticky.

I see what you mean
the load would be carried by the sticky gum rather than the actual tape. The gum's just strong enough to stick the tape to something, not bear load.
