Honestly the 3M clear shield on the front is a good addition. I have had my IS F for just a couple of days and its pretty low to the ground, i.e. it picks up lots of road debris. The new 3M stuff is pretty invisible except on black. With the dark color, you will notice a small line where it stops on the hood. Other than that it should be pretty much invisible. As far as the clear coat sealant, I own collision repair facilities and can attest that its pretty much a bogus charge. They claim that it protects against everything but, to date, I havent seen anything that can keep bird droppings from eating the clear. Something you should know though, Lexus and Toyota do not clear their black cars. So, if you see any foreign material on the paint you need to remove it quickly.
Just my 2 cents....
