No matter how good they are, they'll never get it perfect. You will always notice a difference (color, shade, shine, etc), depending on the lighting and the angle that you look at it, and it will bug the crap out of you. I've had several insurance repairs on regular vehicles, done by very experienced body shops, and I could always tell what was repainted.
T/A spoilers look hot. Put it back on and save yourself some money.
