I'm looking for a way to fill the gap between wing root fairings and fuselage, while remaining easily removable for maintenances. It seems that installing a seal like on the other RV is difficult due to the attash angles.
I have been wondering about the same thing and ordered a clear car door jam seal but unconvinced if it will work OK or looks nice. The gap between the fairing and fues is very little so it is rather a cosmetic thing. I saw a local RV14 that had used similar seal but from Spruce. It did not impress me enough to order similar.
Here is the link to the car door jam that I have ordered, not installed yet.
I used the Van's seal pointed to by Carl in the link and it's worked well over a year of flying. I used the seal only on the leading edge as Carl describes.
