I recieved an email a couple of weeks ago that spoke of a product that does many things including removing bugs and guts. Before I tell you the product, I'll tell you that I was amazed at what this stuff does.
It was developed for the Navy and was a solution that was made with fish oil that they chose. They were looking for something that was basicly a water displacement agent and the 40th combination they tried worked better than anything else. They named it WD-40

Please, try it and see, as I said I was amazed at what it does. Works real well on the bugs and gets rid of any little haze on your headlight covers.
