Doping model frames

Lightly sand the entire airframe with fine sandpaper. Before the frames are covered, all EXTERNAL surfaces MUST be primed with the adhesive dope (diluted at least 1:1 with the thinner; the dope must have the viscosity of water - never use the dope unthinned!). Use a soft flat brush to apply the dope and, when dry, lightly sand all doped surfaces with the fine sandpaper. Apply the second coat and sand lightly again.
