Boy one wing is near enough a whole He. 111. Wasn't the BV.222 the largest, heaviest and longest flying seaplane of WWII and all time? I mean the 'Goose' is famous for being spuce and not flying far?
Must be a fine grit paper; wet 'n dry 900?, there's little sanding 'grainage' visabl in the pics - or small enough that the base/primer paint and the top coats would make it irrelivent.
Love the details on the moedel as is, shows more than pics of the actual Viking show in many repsects - like the collector ring ejection exhaust ports for example.
