Round two was more brutal than the first. The chop shop cleared out fast, no one wanted to risk becoming collateral damage or some crazy bionic assassin's meat shield.
Nebula didn't hesitate to use whatever was in the shop. There were plenty of large blunt objects and pieces to use to deflect whatever Bucky threw her away or use for blunt trauma. They were very evenly matched when it came to skill, but Nebula's enhancements were too extensive, she could take way more of a beating than even Bucky's enhanced body could.
