Do Heater Vents Actually work in a AC Ace in the UK ??
I have found it best to use Rainex on both sides of the windscreen, This gets rid of the water droplets and reduces misting.
During the winter moths the tonneau cover over the passenger side helps keep your feet warm and helps demist a little especially in RHD, even less with LHD. Mind you in heavy rain you expect serious leaks and you know the carpet is 50mm under water as your trousers have long been clinging to your calves.
Seriously, in the 60,000 plus miles I have covered in BEX I have found a handy leather or the back of your gloves will be more effective especially with Rainex than a pair of AC heater vents connected to a period Smiths Heater... Someone had a sense of Humour when they invented Screen Heater Vents
