Was actually one of the easier cappings. Like Marv said just get your alignment right. I glued the whole thin all at once. The ends were the only challenge at the part where the sharpest bend is I would fold that over first. I have a little kink in mine. It's not too noticeable but still pisses me off. The only other thing is I still haven't gotten it to fit right, the top is straight forward but the bottom screws wouldn't line up and the cap sticks up too far where it meets the door cap so pre-fit it first as best you can. `
