Rain-X Bug and Tar Protective Shield works great! Before driving 80 miles to the track last night I sprayed my front bumper, and the area around the back wheels that collects the rubber. Got home and there were plenty bugs accumulated as well as plenty rubber. Normally this would be an excruciating chore to remove. Two quick swipes with the wash mitt and it's all gone! I was a little leary at first because it didn't come straight off with the garden hose, but that's ok because that means it won't come off with a bit of rain.

 

I haven't heard of that product before, thanks for the tip!

This stuff works pretty good too, especially in FL during Love Bug season.
