My problem is with getting the capping on after I upholstered it. I used some foam- backed material product, and it made the pieces too tight/large to fit the door top; too many folds of vinyl, material, and foam. I did a real nice job too. Last night I ripped one apart and I am going to start over. I have experienced in the past that the vinyl can pull out from the fold on the under the trim, so I wanted it hold, but too thick. This time I will leave off the fold on the edge that faces in the car and stop the foam there also and just have vinyl on the outside folded under. I am doing something different on the ends also, but not there yet.
