| (F) Compound Polish — Use rubbing compound (sold at paint stores; shared among friends to avoid waste). Apply a small amount to a cloth and polish lightly. Caution: compounds contain abrasive grit—over-polishing can cut through color to the surfacer and undo your efforts. Beginners should start with just a fingertip amount, wipe, then finish with a clean cloth.\\ | (F) Compound Polish — Use rubbing compound (sold at paint stores; shared among friends to avoid waste).

| My aim with compound is mainly to soften any brush marks. In good conditions, a well-brushed lacquer will already shine; compound plus the next step brings a deep, restrained sheen. Compound lodged in lines and rivets slightly accentuates them. | My aim with compound is mainly to soften any brush marks.

| Earlier we sawed open the exhaust outlets. To suggest internal framing, insert three small triangular tinplate tabs with pliers and paint them; this gives the impression of a hollow interior. | Earlier we sawed open the exhaust outlets.

| On thick wings you can sometimes socket the gear legs, but modern jets have very thin wings with little room. The following retention method works even on thin airfoils: drive two insect pins more than 1 cm into the wing with pliers at the gear station and solder the strut to them. This withstood a ~10 cm drop test in my trials.\\ | On thick wings you can sometimes socket the gear legs, but modern jets have very thin wings with little room.

| Install the tailwheel similarly. Fit the gun barrels and pitot. On larger scales (around 1:30), adding the antenna wire increases realism: embed a small tinplate tab atop the fin and run fine copper wire to the mast. | Install the tailwheel similarly.
