2017 Ram 2500 4wd Mega Cab Laramie Roof Leaking

[FireStar585]

Hello!
I have some leaking in my roof at the Rear Passenger post (c post). I check around the door and that doesn’t seem like that is the source.. I believe the source is the rubber trim on the roof... any suggestions on a quick fix that may help.. like a type of sealant that will get down in those cracks and not look bad..

Any suggestions would be great!
Thanks

I think 5thgenrams only pertains to 2019+ Rams, which could explain why no responses really so far.
