Abstract: A self-mounting automobile window screen for placing between opposing parts of an automobile window frame is disclosed. The window-mounting screen comprises of flexible mesh screen attached to a rubber base and foam rope at the remaining edges. The screen is made to fit a specific model of vehicle and installed into the window channels manually. This provides a resilient but sturdy means to temporarily create a barrier and seal around the window opening when the vehicle is stationary. The screen can be anchored and detached repeatedly without causing damage to the vehicle or the screen. The screen can be conveniently stored in a nylon bag when not in use.
