If you go to the Nusolis website
http://stores.ebay.ca/NuSolis?_trksid=p4340.l2563" onclick="window.open(this.href);return false; you can get a full front end clear protective film kit custom cut for Vibes for about $40.00. This is a cheaper version of the somewhat costly 3M stuff. I'm satisfied with the quality.
It will take half to a full day to put it on the whole front end the first time. Doing it on a warm/hot day and with assistance are both advised.
Not only will this protect against most sandblasting and smaller pebbles, but if you put it on paint that's already sandblasted, it will fill in and smooth out the smaller but numerous pits in the paint.
What's best is to put this stuff on before the paint gets damaged, such as just after you've had the front end repainted. It will also protect the headlights, and you can just replace the film every few years. Nusolis sells the film in sheets if you want to apply it to areas not covered by the kit.
As a $40 diy project, it's hard to go wrong with this.
