Query: Turtle Wax didn't work

I carefully followed the directions, and Turtle Wax Bug and Tar Remover did absolutely nothing to remove the bugs from the front of my car.Darn, I should have read these Amazon reviews before buying this stuff. My fault. I bought it thinking the Turtle Wax brand name would ensure reasonable quality. I won't be buying any Turtle Wax products in the future.
