I've been reading up for a few months now on this stuff, measured, remeasured, and measured again, and finally decided today was the day to order. I went with a combination of 3M and AD Nano, both in bulk and I purchased at price per foot.
I plan on doing the front and rear door sils, headlights, mirrors, the black trim on the upper exterior B & C pillars (that stuff scratches super easy), and the front bumper with 3M, and the hood with Nano. I was back and forth for weeks on the width to order for the hood, but just recently decided to do the whole thing.
I also considered many options for templates, including thin mil painters plastic, seran wrap, old cotton sheets, overlapping blue masking tape, etc etc. There's a guy on a Bimmer forum that made his templates out of old table cloth. I chose overlapping blue masking tape using a pencil to outline on the B & C pillars, and cut the rest of the pieces in place. I plan on wrapping the edges of the hood as well.
I paid $180 for the hood piece, $90 for the front bumper, and $70 for the 4 door sils, headlights, mirrors, B & C pillars, and I should have an approx. 4X30 piece leftover. In materials I probably only saved $250 or so over ordering the kits and doing it myself. But the big savings will obviously be with me doing the install myself. From what I've seen and read to get these same pieces done it would be in the $1000 range for materials and install.
I'll be installing the pieces over the next couple of months and I plan to post pics. Any WK2 owners that live near the Travis AFB area feel free to come give me a hand. Beers on me..after the install of course
