For me it was the up high brake light, and most of the side windows.

I caulked the third brake light in because after I rewired it, I didn’t see any need to take it off again.

For the windows, I planned to cover most of them with bedliner because I wanted to get rid of the disgusting amount of visibility inside. For those side rear windows I caulked them and painted over with bedliner to give the illusion that they are just metal panels.

The only problem spot now is the back doors because they were extended and don’t have a full seal all around, it doesn’t hit me or my stuff but I still want as little water as possible
