Moisture under the frunk/froot lid

[Tony_Br]

I have noticed that my 718 Spyder gets somewhat damp, on the underside of the frunk lid and on top of the battery compartment plastic cover, and also actually within the bulkhead area, underneath the plastic cover (e.g. around the battery tray) after standing in rainy conditions.
I am a little concerned about the long term effects of standing water building up around this zone, so some questions:

1. Where are the drain channels - presumably under the front lower edge/corners of the windscreen?
2. The outer ends of the battery compartment plastic cover appear to be designed to divert rainwater somewhere beneath the lower corners of the screen/cowling - but the exact positioning of the ends (the pointy corners) looks open to question - should these corners be above or below the semi-fixed rubber seals which are attached to the channel on the inside each front wing? (I attach a couple of pictures - driver's side and passenger's side).
3. I was thinking of fitting a proper sealing rubber strip to the vertical edge the plastic screen cowling (see picture), which kind of seals itself (badly) against the frunk lid, in order to reduce the amount of rain splash that finds it way under the lid. I would of course ensure that the screenwasher jets are not obscured. Would this be a bad idea - is the volume intended to poorly sealed in order to aid airflow/ventilation there?

Ideas welcomed!

This is just my 987.2 (2009) experience of this area, so may be irrelevant. Sorry in advance if so.

The area by the battery (all covers off) are either side of the battery on the bottom of the bulk head floor. Thus, any rain/water will find itself down to the drain holes and out of the car via the tubes and the road.
To see/locate/clear these holes is not easy but they are about 10mm diameter but often covered with rubbish and this could lead to water not draining away.

Do you wash the car with a power washer? This could flood the screen/bonnet top very easily.

Often in poor weather (about now) I will get condensation under the bonnet surface.
The bottom of the front boot under the carpet is always dry.

On my car there is a need to refit all the plastic shields and strips correctly to ensure the water can flow off and clear the area.

Hope this helps you and someone else will come along with comments to your specific car.

Thanks for responding.

Power washing - yes, but (a) infrequently and (b) I am careful about pressure used and areas sprayed because my car does have 100% PPF coverage.

The location of the drain holes is definitely of interest - I regularly remove the battery compartment cover and use a long/thin vacuum cleaner to remove any build up of leaf and pollen related debris in the bulkhead zone. So knowing the location of the drain holes would be useful in this task, especially if I have to remove anything to get to them.

The correct refitting of plastic and rubber shields is my other main interest, as I know that getting these things wrong will almost certainly make things worse.

So - 981/718 experts step forward!
