Can anyone recommend a good Bug & Tar remover? Now that Spring/Summer are here in the South the bugs that are the size of small birds have decided to cross the road and met their demise on my front bumper. I remember using something years ago that almost seemed petroleum based and left a film unless the car was washed. So if anyone has some experience/advice...let me know. Also if you can let me know where you purchased the fabulous product that would be appreciated. Thanks.
