improving mesh for reflection

any idea on how to improve the mesh. ( airplane ) The reflections look not perfect that’s why. ( without adding vertices nor subsurf )
Thanks Michael

Well first I would say that you could eliminate about 100 triangles that might be messing it up. It could take a ton of time but you can either do that or start over. Cause I see a ton to fix and subsurf and tris don’t mix well. Good luck! Oh, use the Ctrl+J command to join two together.

press a once or twice, to select everything, then press alt+j, that should clear everything up
