Hi, I'm weighing whether to get a CPL for a dashcam or use a dashmat. I'm starting to lean towards getting a dashmat for the added benefit of protecting the dash from the sun and possibly lowering the interior temperature of the car. I was then wondering is there any added dashcam benefit of using a CPL in addition to a dashmat or would using both be redundant for purposes of the dashcam?
And regarding dashmats, my understanding is that it's best to get the darkest color possible (black) to minimize the reflections in the windshield. But I'm confused on what's the best material for the dashmat (again for purposes of reducing the windshield reflections and glare). The main choices seem to be carpet, velour and suede (like mentioned at
