Extended Hood and wipers??'s

[Coupe Devil]

I really like the look of an extended hood. But needing the ability to drive on the street.. I will want the option to run wipers if I ever get accidently caught out in rain. I wont intentionally drive the car in rain but you get caught out sometimes.. Has anyone ever trimmed the back of the hood where it goes to the windshield? How far back do ya need to trim . Anyone have any pictures of a car like this?

Thanks
Bradley
