Sorry if this has come up before, I did a half-assed search and came up empty.

I don't typically leave my car in the rain but today I decided that I would in order to effortlessly clean the garage dust off it and also make sure it doesn't leak water. Well, turns out it does leak water.

Whatever sealant that was used between the fixed door glass and the divide channel for the drop glass has some pin holes allowing some rain water to leak inside and slowly drip down the door panel and onto the carpet. Not terrible but I don't want any leaks should I ever need to have the car out in the weather. This has happened on the passenger side of my car once already and I used a thin line of clear silicone on the outside to correct it.

I'd like to fix this permanently on both sides of my car. The clear silicone looks awful. Is the divider able to be removed without removing the fixed glass? What sealant should I use?

Any help is greatly appreciated.

Cheers,
