What do you use to cover the tool to keep it clean and contaminant free during the bagging process?

The use of masking tape to cover tools during the bagging process is particularly effective for several reasons. Masking tape is designed to adhere well to various surfaces without leaving a sticky residue when removed and provides a relatively airtight seal that helps protect the tools from dust and contaminants. It is also a quick and efficient method to cover tools, allowing for easy application and removal while ensuring that the tools remain clean until they are needed for assembly or maintenance.

While other options like plastic wrap or cloth covers can be used in certain scenarios, masking tape offers a balance between ease of use, effectiveness in protection, and cleanliness, making it a preferred choice in many aerospace assembly environments.
