I was bummed to miss this but I ended up buying the whole kit from Amazon and doing it myself yesterday. Really glad I did. I was really impressed with the sprayer and extension wands, etc. However, I can't imagine doing more than one car per day, though. It was hours of crawling around under the car in awkward positions on cold concrete, particularly futzing with those skid plates and the at least 3 bolt sizes holding them on (WTF were they thinking with that design? And, of course some idiot assembled them wrong before).
Anyway, I was additionally able to remove and put anti-seize on all of the skid plate bolts and do the same with the KDSS valve guard (at least 3 14mm bolts holding the little plate on, funny) and coat the valve itself with grease. Also dropped the spare (first time ever done on my car, tools and spare were brand new/unused clearly) and clean it all up, shoot everything under the spare, hit the chain winch, etc. Just really took my time and got as thorough as reasonably possible. Really nice to hit everything BEFORE it's frozen/seized/snapped off in 10 years!
