I think some paint matching the radiator would be nice. Mask the vent, and paint the other. I know the paint is not going to actually adhere to the tape, but I am assuming the paint film will hold together over the tape.
Plastidip spray paint can be nice. If you don't like it, you can peel it off with your fingernail. Obviously you need to mask a big area when using spray.
