Tape the cabin top and window lens (if the protective layer has been removed). "Push" the tip of the silicone gun or tube. Don't pull it. Keep a small bubble of silicone on the front of the tip. That will ensure you are forcing silicone into the gap. Once you've injected the silicone all the way around, use the back side of a plastic spoon to smooth the silicone into a concave shape. Keep the spoon moving smoothly. Don't start and stop. If you find a gap or two in the silicone, fill it quickly and run the spoon around again.
Press the spoon fairly hard. It will remove the silicone immediately on either side of the gap. Let it cure a bit. Check the cure by touching the excess silicone on the tape not in the gap. When it is moderately firm but not completely cured, pull the tape making sure you pull away from the gap. The result should be a really nice "factory" look. Dennis C.
