I use to use a light spray wax / paint sealant as a final wipe down, but that is no longer used / needed since I started using the Tar and Bug remover.

Now I have not noticed if it helps prevent future bug issues, but I really doubt it... Since I am wiping it down with a rag, the amount that stays behind as a coating is minimal so much so, that by the time I use the engine again one week later, I never see any kind of oil sheen on the water when I dunk the boat again. Thus it must dry up quite well after a few days setting in the Florida heat.
