Wait Trek should recall all Domanes because your LBS put electrical tape on your wife's seatpost causing the clear coat to come off? So if you put a bumper sticker on your car and it damages the paint should all those same model of cars be recalled? I would keep pestering the bike shop because Trek has nothing to do with your issue. It was the shops fault for not taking off the tape once done with whatever they were doing. We normally just used a sharpie to mark the position. At the least they owe you a new seatpost as the frame it's has no issue for a recall.
