Great to get your thoughts. I've already got the one fan on the back of the mirror, but am just trying anything that might get that extra bit of steadiness.
I spend a lot of time blaming the atmospherics for poor seeing whereas a good proportion might be due to that layer of warmer air hugging the front of my 2" thick mirror. I guess I'll only know if I try it out rather than theorise the answer... Any practical experiences out there?
If I installed a pair of fans to blow across the front of the mirror, I'm wondering if I really need extra exit holes opposite the fans. My mirror sits in an open tailgate/mirror box design.
Thanks for your patience on what must be an old topic...
