Yep, if you run it in carefully, let it harden, then sand back, it will do the job.
BTW, the Corsair was originally one of Monogram's early 1960's kits, which were innovative at the time. I believe the idea was to provide a folded wing option for modellers, and folding wings for children, who could play with the finished model. Hence the not so perfect fit etc, nearly 50 years later.
Some of the other kits of the period from the same company, had retractble undercarriage, working bomb relese etc etc.
