Can you insulate the car with a photographic mirror?

Of course. When the sun shines directly on the car, a camera reflector can be placed on the windshield. This product is designed to prevent sunlight from directly illuminating the objects and interior of the car through the automobile glass, and to achieve the purpose of cooling and heat insulation by reflecting sunlight. There are gold reflectors, silver reflectors, white reflectors, black reflectors and blue reflectors.
