I'm about to tackle putting the Alum Window Drip back on to my car. And was wondering if there were any special technics that someone might share that can make it easier. It seems a bit tricky. Should I first put caulk or some type of sealant between the aluminum strips and the body before putting the Alum Drip on? It seems that this piece is somehow pressed/snapped onto so that it covers both the aluminum strip and the body. Any suggestions would be appreciated.
