Grip the outer lip of the molly bolt with a pair of needle-nose pliers. Twist part of the lip away from the wall or door surface and wiggle it back and forth using the pliers until you break off that part of the lip. Continue around the lip until you break off all of it.
Insert the end of a screwdriver into the molly bolt hole and push the bolt into the wall or door, underneath the surface.
Dip your finger, or the blade of a putty knife, into spackle and spread a coat of it over the wall or door hole. Smooth the coat with the putty knife's blade. Follow the spackle manufacturer's instructions to allow the spackle to fully dry.
Fold over a piece of fine-grit sandpaper and sand the dried spackle. Use light, short strokes until the spot is smooth.
Wipe away any sanding dust, using a cloth. The spot is now ready to be painted.
