Hello,

Have ever thought about "forced panelling" technique used in plastic modeling? Basically, you lay a masking tape anterior to the panel lines then using an almost dry brush with darker color of the main frame brushing AGAINST the tape. The paint particles will be "sweept up" against the tape producing a nice sharp panel line. This technique works great on 1/5- 1/6 scale planes. Anything larger will need the technique outlined in previous posts. I have done so on my O-1 Bird Dog and it looks very convincing. DP
