I've used this on two separate cars with great results:

It's only been on three months so it's too early to say how it'll hold up, but so far this is the best solution I've come across. Everything else I tried showed yellowing after a week or two. The key product in this kit is the spray sealant. Wipe New does the same thing (which I may try on my E90 since I haven't used it yet) however I just thought this spray would be easier to apply evenly.
The first time I used this kit, I followed the directions exactly and the results were great. The second car I did, I added a few extra steps and got better results. I started wet sanding with 1000 grit sandpaper, then moved to 1500, then I used the cleaning solution in the meguiars kit (which is abrasive), then applied PlastX polish with my DA polisher. At this point the lights were very clear and smooth, but after applying the Keep Clear spray they really shined and looked new.
