Is 2 days not kind of normal for fitting a fibreglass bumper? By the time the original is removed, new one offered up, holes drilled/cut, areas masked up, filler set, sanding and prep done, paint booth set up, painted cured, put back together, clean up, polished etc etc. For OEM parts i would expect it to take a full day, drop off in the morning and pick it up the next afternoon.
Am I being too lenient?
