I finally was able to set up a Mobile Ranger visit last week for the rear spoiler install (only 9 months after delivery). Experienced tech who brought out 2 of the current rev spoiler. He used the flexible purple guides on each corner of the trunk lid, did some careful checking and fiddling, cleaned the edge of the trunk lid, peeled off the tape, and did the install. Then used his heat gun to cook it a bit. Perfect installation and no gaps or lifting. He did note that the 1st gen spoilers were pretty bad--twisting and popping off.
