Personally, I like the name "Invader" for the A-36. Different designation, different name. Even if that designation was budgetary legerdemain.
F-16 pilots call their ride "Vipers".
Aircraft bondo is very heavy. A neighbor's uncle worked for an airline and brought half of a can to his nephew for the kid's car. Much heavier than auto Bondo, however 200mph is not a requirement.
