Is it normal for these cars to get so damp and wet on the inside of the windscreen?
It's really getting on my brass nips now .

I put some damp traps in the car over winter.
One in the cabin, one in the boot.

Ah it's a joke. Highly annoying . Doesn't help that the Demister vents are crap.

Have you checked for water ingress? Under carpets or in the boot?

Using the Aircon to demist generally creates excess moisture, I try to avoid and never had moisture issues on my 2010 model.

No, absolutely not!
Check the following areas:
- Lift up the foam of the hydraulic pump and check for water around the battery
- Lift the floor mat on both sides of the car, driver as well as passenger. In rare cases there is an issue with a connection to the Aircon box, where water continuously can run below the mats.

I thought the Aircon dried the air in the car?

Sorry but this is incorrect.
The a/c will de-humidify, as long as the drain from the evaporator is not blocked and the water can get away.
Moisture vapour held in the air of the car condenses on the evaporator coil with the a/c running (sited next to the heater coil/ matrix in the fan housing).
It should then drain away to ground via the drain tube/ pipe when enough water is produced.
The only time it can be a problem is when the a/c is turned off with the evaporator covered in condensation. The evaporator will then warm and the fan will blow back the moisture as a vapour into the cabin. Then it will condense back into water within the car wherever the dew points are, generally windscreen and windows.
The secret is to NEVER switch off the a/c whilst the fan is operating if using for demisting. Keep the a/c on until you switch off the car/ blower fan. If you do all you will do is fire the moisture back all in one go, so seemingly creating more moisture.
If there is excess moisture inside the car either you have a leak coming from outside, or the a/c is draining water back into the cabin.

All good things come to those who wait. I'm really impatient which explains a lot.

I used aircon once to demist a MR2 shield. It cleared, but as soon as i switched it off the screen instantly fogged over. Very dangerous.

See the post above. You must have switched the a/c off whilst the evaporator was saturated.

Yes it does, the instructions for my wife's Ford Focus states to use the air con to demist quicker. It has a heated windscreen and this should be a feature on all cars as it is amazing, it clears the screen within minutes, no scraping and no stopping up the road to fart about scraping again. Brill. Shame BMW didn't get it.

Ford patented the heated windscreen and wouldn't allow the patent to be used by any other manufacturer, apparently. Best thing about Fords IMHO. Windscreens cost a few quid to replace, though.
