Turtle Wax Bug and Tar Remover will get the bugs off the front cap pretty good. Smells like it has some Varsol or Kerosene in it. I just returned from a 2,000 mile trip complete with southern bugs of all species. Bugs came off pretty good just soaking with water a few minutes then using Meguiars yellow car wash soap and the typical WalMart blue brush. I try to keep lots of wax on the front, even if its only spray on wax just before a trip.
My boat gets the 3M wax as well. The Meguiars Premium Marine products are very good. My boat stays in the garage except during actual use, which isn't near enough.
