Vents in bonnet - show or have a purpose?

[dom101]

So was just wondering the vents on the bonnet which sit above ecu and battery area, have they got a reason as rain and water from washinv car easily gets in, or just for show as seem some g40s with bonnets smoothed

They allow fresh air in for the cabin heater and fan.

[dom101]

does it matter if they get smoothed  over? or is it not a big issue? as the scuttle tray doesnt cover all the bay,was thinking watercould esily damage somehting?

There's meant to be a plastic cover forcing water to run either side and out.
