bug or tar

What's everyone use. I posted this in car care products but got no response. I just bought some of the turtle wax bug/tar remover but haven't tried it yet.

I've got these nasty ass water spots on my car. I bug and tarred the entire hood, and made it brand spanking new after using VERY much elbow grease. Unfortunately, I have yet to finish the rest of the car....i.e. doors/roof/fenders......and this would take a while. I was wondering if there are...

Well...it wasn't the best choice, but i took a 6 hour road trip to LA in my RSX, and now my front bumper and some parts of the hood are covered w/ bug splats. I do have a can of bug/tar remover spray...but my question is, would it be wise to use it on the whole bumper cuz i've only used it once...

What's a decent brand? Looking for something available locally...Walmart, AutoZone, K-Mart, Pep Boys, whatever. thx
