Quote: I'm seeking advice on how to make sure they're living up to their end of the rust repair bargain.
Quality is about getting the panels aligned properly -
Trunk and hood should line up nicely with rear quarters and front fenders - Check the edges where they meet, especially at the corners. The doors should appear perfect looking down the side of the car, not cocked or sticking out/in. Check ALL the gaps everywhere on the car. They should be even. Anything that looks off even a little now will be more visible after paint.
