I can heartily recommend to everybody, a product from Meguirs (sorry if its spelt incorrectly). It is a polishing putty, it removes tree sap, bugs and road grime easily. All you do is spray on the spray that comes with it and rub the surface with the putty. You end up with a paint finish that is smooth as glass and takes no effort to polish. The results are actually amazing. I used it on my last car and after I polished it, it looked brand new (at the time it was 10 years old). I am sorry I can't remember the exact name of the stuff, but most GOOD stockists should have it.
I have been using it too and the results are good.
