Blocking Off Sun Penetration Into the Car
When the sun is overhead, it penetrates right through the screen into the car. The brightness can be blinding. To block off this ray, use plastic sheet screens. Visit a store to purchase a plastic sheet or screen.
The plastic sheet glues automatically to the screen and the color blocks off the sharp ray of the sun. Alternatively, use films utilised in greenhouse projects. For this, however, scotch tape is necessary to fix the film to the screen firmly. A simple and easy hack.
