Thanks for the comments. First I drew the thin panel lines and rivets with a fine tipped Sharpie marker. Get a black carbon pencil and scrape with a blade to get black carbon powder. Rub all the lines with finger dabbed in the powder to enhance panel lines. Use silver Sharpie at panel corners and rub silver with carbon to give oxidized aluminum and paint peel look. Same technique used on weathering and runoff effect. This plane is coated with Minwax satin urethane from a spray can but, Nelsons Hobby Products makes a good nitroproof flat clear for glow fueled planes that works well also. Took about 20 - 30 hours to weather it (top and bottom) but was a lot of fun and really worth the effort. It no longer looks like a toy and often mistaken for a Yellow, Ziroli, or Platt. Ha! Paul
