Pretty sure I do not have an issue with the drains. However I tried snaking out the drains with a long thin brush on a flexible wire made for this purpose.

The right rear was fine. The brush head poked out from the back of the open roof frame. The left rear did not. I don't have any signs of leaking in the trunk area, but this kind of worries me that it's leaking inside the headliner even though there's no signs of that.

I can't see where the front drains are in the open roof, but I do see the rubber nipply things under the car so I can try pushing the wire up through those.

Second q: I bought some "Sil Glide" silicone grease for lubing it up. Prior owner had used that garbage spray white grease that gets absolutely everywhere and it looks dry, but opens and closes fine with no weird noises. Where should I apply this stuff?
