I'm a nostalgia builder, too, and I congratulate you on sticking with this kit. A lot of guys today just avoid them, but it's always great to see someone show that even a kit like this, can be made into a decent representation of the subject, with a little work.
I've got the AMT F4U in my stash, started years ago, and stalled at the point of finishing the interior. The cockpit is pretty bad, though under a closed canopy, with a pilot, you can't see it. But the seat looks like something out of "Star Trek".
I think AMT's cars were of better quality, consistently, than their airplanes.
