Good fit all 'round, little need for filler. I added a small strip of styrene to represent the metal strip between the gun doors, will sand this back later.
Cutting the ribs on the lower wing will help improve the fit of the engine nacelles, yet filler will be needed to blend them in. The fit is never good on any kit of the me 262 I've build, except for the tamiya kit maybe, but this will eventually be acceptable.
