This one was started around 1990 and was well along when I dropped it and chipped the tail. I became depressed. I set it aside for later. December 2024 is later enough, I guess. 
This is the state it languished in all those years, with the exception that the tail has just been repaired using Aves Epoxysculpt. I cut more of the fin off and cut a notch crossing the separation line to add strength.
Quite proud of my ingenuity, but later that night I asked myself, why didn’t I just cut the top of the fin off one of the 6 other Hasegawa F-106 kits in the stash. We are always overthinking the problem!
A closer view of the magnificent repair:
The air data probes on the fin were replaced with music wire. The canopy fit is not important as it will be posed open. The sealant decals came out well, I think. The ALPS prints on a continuous film, so I made cuts around the outside and inside and removed the clear film when it released after being wet. I lost the first decal learning how to do it but I always print extras and the next two attempts went well. Flooding the application area with water made the difference. A cotton bud was carefully used to get rid of the excess water and Micro Sol was then dropped on. The narrow decal is easy to displace. Once the Micro Sol had expired I dipped the canopy in Future, which of course was the second time the canopy had gotten that treatment.
