yea, wd-40 is great for removing bugs/tar. You could also use any of the special products for removing them, they all pretty much just use a base solvent equivalent or very similar to kerosene. I hate using the stuff because it can damage your paint- I wont use it without a running water hose within arms width and a bucket of soap. Get the wd40/specialty product onto the bugs, scrub scrub scrub, rinse, wash, rinse, wash, rinse. I don't like the idea of anyhting i'm using to CLEAN the car STRIPPING the paint off- hence the double wash.
