1. Will RainX affect a radar detector's range and capabilities?
2. Will it increase, decrease or leave the same, the distance for laser to get a reading?
I really really doubt it will increase the range. But for the decrease, i do not know.
Shouldn't do anything at all. It's totally transparent and it's completely non-metallic. I think it's very safe to say that RainX does less to reception than simple moisture.
Rain X is just like a wax that makes your windshield slippery....so the rain drops will slide off...I know for a fact that it will not decrease nor increase your sensitivity... 8)
