I used to think that too , until I restored my first old Monogram kit and found out how nice they can look !
Back when I did the mock-up it was obvious that without fenders those rear wheel openings would really stand out , so I did some looking and decided to make some filler panels like these .
Not keeping with my "Box Stock" build but they will really improve the overall appearance . I made a quick little mold and used my Vac-U-Form to make the panels .
Trimmed and test fitting the panels .
Finished and painted to match .
