This. I'm not a physics expert... okay, I know nothing about physics except for when I stub my toe in the dark... but I'd think bending the light around an object as small as a paper clip isnt the problem. It's not the light bending around something, IMO: what makes something "invisible" is the ability to
see through it. Sure, with a paper clip on a solid-color background, you can bend the light and it looks invisible. And if you're talking about the clear blue sky (or white clouded sky), having a plane covered in the stuff might make it harder to see. But if a tank is rumbling across a green field with trees and a blue sky, unless you can see
through the tank and observe non-moving tree trunks, any reflective material will simply make it look like a giant patch of grass or blue sky that's moving around.
