When I bought my car, the front clip was severely pitted from bug guts left on the car in Louisiana. Anyone from the south can tell you about the love bugs in spring and summer and how the acid in their bodies eats clear coat if you don't clean them off right away.
I bought a can of FW1 Detail spray at a gas station once, it worked wonders in preventing those little bastards from sticking, I would just wipe them off with a damp cloth after a long drive and wash the car at normal intervals. I would recommend that product to anyone that has to clean bugs off their car on a regular basis. The product itself is expensive and may be gimmicky, but it is very convenient to prevent bugs from sticking and becoming difficult to remove which was worth the cost to me. Just my 0.02$
