Secure the Folded Flap with Tape

What happens here

To ensure the newly created folded flap remains open and stable during the spray painting process, secure it with additional pieces of production tape. Apply short strips of tape at strategic points along the folded edge, effectively 'tacking' the flap in place. The presenter demonstrates applying tape in three places, and advises repeating this entire masking process around the entire window trim (all sides where spraying will occur).

Goal: Stabilize the overspray flap to maintain its protective shape.
