RAIN-X

Here's a description from the official website:

Original Glass Treatment ^TM

The invisible windshield Wiper®

Rain-X Original Glass Treatment dramatically improves wet weather driving visibility. Simply apply the treatment to exterior glass and watch the raindrops fly off your windshield while driving. Rain-X helps improve visibility by repelling rain, sleet and snow.

• Improve all-weather visibility, safety and driving comfort
• Helps easily remove frost, ice, salt, mud and bugs
• Apply to exterior glass

In tests conducted by a major university, better visibility improved driving response time up to a full second or more. At highway speeds, that’s almost four car lengths of extra stopping distance!

Seriously though, if you haven't rocked with the rain X you are missing out on your safety! this shit works. you need a hook up drop on by and I'll put this shit on your car... seriously ask Trav. 8 Beards and a mustache. I don't give it a full 9 because the stuff wares off bimonthly. but it's still a freaking 8.5. SHIT ROCKS! It's like driving with MOSES the rain just parts right in front of you
