On the advice of some builders who have had gear-up landings, I went with a plywood nose pad around the front of the gear door. This gives stopping ability, but more wear protection than a small puck. With the fairing around it, it won't add much drag.

John spent a lot of time tweaking the doors to work just right. His finishing work is excellent. You can also see the sealing box here. If you look closely you can make out a small fiberglass lip that extends up from the gear box. The cover fits into this slot, and with some RTV sealant will completely seal the space.
