In Stages 83-91 (Pack 11) of our 1:8 scale Lamborghini Miura build, we attach the Headlights, Body Hinges, Eyelashes, quite a few front Grilles, as well as the front Fog Lights and turn signals. The third Wheel is assembled and we install the Boot Lid and some structures inside the Front Body and Rear Body sections.

I put about 1/8 inch oil in a cap and dip screws in. Keep a paper towel handy to keep your fingers and screwdriver clean. Cap must be taped/secured to work surface. I use cap from medicine bottle. A milk carton cap would work.
