Prime rear window exterior trim.

I have not seen any trim like you are describing used on PRIME, but the gap has to be there for the hatch to fully open and close. Anything you use to cover the gap has to be flexible enough so as not to obstruct the hatch movements. It almost has to be made of something that is squashable like a rubber weatherstrip around the windows. I don't know how that is going to look aesthetically. If you find anything suitable to experiment, yeah please let us know. The pine needles, I can just blow them off, but I sometimes have a problem with ice getting stuck in that gap.

 

I think he means the gap at the bottom between the glass and the spoiler. No interference there, but I share the annoyance with leave falling in there. I have not found anything to cover it.

 

Oh, you mean this gap and not the one on the top of the glass hatch where it is hinged and meet the roof panel. Yeah, mine is full of maple seeds. I need a good car wash. I think some kind of weather strip would fill this gap easily. Black flexible stick on type molding trim may also cover the gap, but I don't know what that would look aesthetically.

 

I just use a shop vac and carefully run it across the lower glass also in the area under when the hatch is open. I also do under the hood and lower windshield. I get a lot of pine needles.

 

I blow it out with compressed air occasionally. My concern is that the debris in there will hold moisture and cause rust in the low spot. But to do it right, I'd have to blow it out almost every day. I suppose the gap is to allow for flexing, but you'd think they could a filled it with some kind of rubber compound.

 

I just measured the gaps. The bottom one is 1/4" wide while the top one is 3/8" wide. I think something like this or this will fill the gap and still be flexible enough to allow movements. The second one is for the front windshield, but may work. I just don't know how it look aesthetically. Not very expensive, I may buy and try inserting it without using any sealant or adhesive. I am not too worried about the bottom gap, but the top gap during winter months when the chunks of ice getting caught is more of concern for me.

EDIT: I just ordered those two trims I linked. I will let you guys know how it works to fill the gaps. But before that, yap, the car really needs a good wash.

 

Cool!!! I'm with @Rodney.E. Let us know how it works. I'm definitely interested.

 

Where is that drain holes? Any pic to point me to them? Are they within that gap? Now come to think of it, I don't know where the water is going when it hit that gap...must have drain.

Not that I do frequent car wash, but I know any stuff like leaves and dirt in the lower gap cleans easily with a jet of water. I have more of problem with leaves, dirt, dusts, pollen accumulating all around the the hatch door which is harder to wash.

 

Do you mean this? If so, where is this drain connected? Water from the top of the rear window ends up here?

 

About the gap on the top of the hatch, not at the bottom, here is what my car currently looks like. Those pollen, dirt, leaves, bugs, and all kind of debris that fell onto the roof of the car all end up in this chasm. I admit that I have not washed my car since the day I drove it to home at the end of Feb. But this is all from mainly just sitting on my driveway. I did not drive the car on a dirt road or into national forest area. The area above and the side of the hatch is always dirty like this, and it can not be washed off easily by automatic car wash. If I can somehow cover the gap at the top of the hatch, it may stay little bit cleaner.

 

I'm pretty sure this area just runs down the sides of the hatch area to the outside of the gasket.

 

Yes, plain water will just run down around the hatch and go down over the rear bumper cover. But if the water is carrying all sort of debris with it, they all ends up at the top of hatch in the photo above or caught on side or the at the bottom corner of the hatch as shown here.
