What should be done to the structure that will be covered with doped fabric after inspection?

After inspecting the underlying structure that will be covered with doped fabric, it is essential to treat it with a protective coating of paint or varnish. This step is critical because it provides a barrier against moisture and other environmental factors that could lead to corrosion or degradation of the structure over time.

Applying a protective coating helps to preserve the integrity of the materials, extending their lifespan and ensuring they remain structurally sound. The paint or varnish also serves to create a smoother surface for the fabric covering, enhancing adhesion and contributing to the overall durability of the finished assembly.

This approach is particularly important in aviation maintenance, where the safety and performance of the aircraft are of utmost concern. A properly protected structure will help prevent future repairs, reducing maintenance costs and enhancing the safety of the aircraft.
