well the actual dock is very slightly lopsided, but the left edge has a larger angle to the left, which happened as I purposely angled the left edge lower so that the mute and volume buttons on the left could be accessed, but I ended up angling the left edge to far left as well.
I have filled the edges and straightened them out, I'm very happy with bottom edges and right, but left is still off since there's just too much of a gap to fill with filler. I could use more putty I guess, but not sure if it's worth it.
Here is the iphone saran wrapped as the filler dries and then after I shaped the edges with 80 grit and then sanded with 220.
I will soon sand with 320 and feather in from filler to plastic the best I can and then Prime.
