What is the result of not tensioning the fabric properly during application?

Not tensioning the fabric properly during application can lead to visual imperfections such as wrinkles, bumps, and sagging areas on the aircraft's surface. These imperfections can affect the overall aesthetic of the aircraft and are often indicative of improper application techniques. Additionally, failure to properly tension the fabric can compromise the smoothness necessary for optimal airflow, which can also impact aircraft performance. Proper tensioning ensures that the fabric is tightly and evenly applied, which not only enhances the appearance but also contributes to the durability and integrity of the covering. Therefore, addressing tensioning issues is crucial for both visual appeal and functional performance.
