Hi All, I just bought and downloaded a Marek P-51B Mustang model. One good diagram came with this model, but no written instructions or guidelines is provided. I learned from reading a review in Cardmodels Online Magazine that parts with red numbers should be glued to heavier card stock. What I don't know is what a red dot on a part, or a red dot next to a part, is suppose to mean. Can anyone tell me what this means? Does Marek use any other symbols?
