I'd suggest 3M Paint Protection Film as an easy and less expensive alternative. It used to be called "Clear Bra".
It is supposed to go on with soapy water, squeegee out the air bubbles much like window tint. There was a DIY thread in the Single Speed forum and the guy did it with just plain water because there was so little of the stuff applied.
O'Reilly has rolls of it in several widths.

The helicopter tape is overkill IMO.
