Filling Seams and Sanding the Aircraft Model Removing the seams
and joint lines is necessary when building model airplanes. Many
assemblies often result in unnatural gaps or cracks in the
fitting. Among the most common problem areas are the wing roots
and the mating lines between both sides of the fuselage. To
produce an authentic looking aircraft model, I recommend the
following technique. To begin, you will need various grades of
sandpaper, including 600ALO, 400ALO, 320SIL and 150SIL. Other
necessary tools include; a sharp hobby knife, a paintbrush and a
container with a small amount of water. We will also cover the
use of model putty and Tenax-7R, a fast-dry formula used for
welding plastic scale model parts. I should remind the reader
that when building model airplanes using hazardous materials, it
is very important to have plenty of ventilation around the
working space. You should also pay close attention to all the
warnings that come with each chemical, usually found on the
product container. This techn
