The only missing parts on the Black Widow are the radar antennae. They will be glued last to avoid breakage.
Enjoy these before the decals are applied.
Decals add a finishing touch to a build. Using 20 year-old decals might be a problem.
The first decal was soaked for a minute and nothing happened. I had to use my neuro surgeon skills to work it out.
With this experience I decided to wait and see the final result before proceeding with the other decals and studying closely the instructions sheet.
