I can completely relate. It's been about a year since I gave my X any attention other than a touchless wash, or the usual self-serve blast-down after 'wheeling. Last time I actually did it myself at the house it took most of the day.
I always plan to put down at least 2 layers of Liquid Glass but after washing, trying to spiff up some of the more obvious trail pinstriping, applying Back To Black, and laying down and polishing one coat of LG, my arms are pretty worn out. I take a break and clean and Rain-X all the windows, and at that point the day is pretty well gone, the wife is sick of me paying more attention to the X than her, and I'm just beat, so that second coat never gets on there.
I'm ready to pay someone to detail the thing next time. It needs the floor shampooed after at least 2 instances of skanky muddy water coming in too. I had planned long ago to treat my X to a full detail job on it's "birthday" every year, but never followed through.
