I ordered an Alphagvrd skin for my 400mm f4.5 on May 28 and just got it today. You are instructed to scan a QR code which brings up a diagram of the lens and how the skin pieces to onto the lens. That's all the "help" you get. I found
this video which was helpful. The associated pieces of the skin are labeled A1, A2, A3, etc, B1, B2, etc and C1, C2, etc. (I HATE using the phone for this and would have much preferred to have the diagram on my large PC monitor. Oh well.)
HOWEVER, the pieces of the skin are laid out on sheets
with no labeling at all of any of the pieces!!!! The hood piece was easy to ID. As were a few of the pieces that had cut outs for the various texts on the lens, or buttons or such. But the labeling was of no help at all. Still I muddled my way through it. Why do I have so many left over pieces.......
......even more than those that were to cover the rubber rotating rings I had decided when I ordered it that I wouldn't cover.
Here is how it looks now:

I much prefer the camo look of
@jadewolf 's lens! But I do like the pre-cut pieces. Just wish they were better labeled. I probably won't do this with my 600mm TC due to the curved nature of that lens. I'm much more inclined to get a LensCoat (I have used several and had NO problems with them) or something similar.
