Outside Temp Sender & Water

I know the temperature readings are affected by water but I had the oportunity to watch this today. I went to the East European car wash and arrived with 19c showing on the dash. As they applied the power washer I watched the display slowly decline to 15c.

I don't know about anybody else but my display always over reads by 2c (confirmed by 2 commercial outdoor displays and my own outdoor thermometer).

During the journey home the display has climbed to 16c and my home thermometer reads 17c.

Now I just need a way to make it permanantly dampish to bridge that 2c

This is sad, but I just went out to the car and got a reading of 12C. It was raining and got wet . Checked on home weather thingy and got 12C. Is this lucky or what. The thing is, these sensors are not accurate, even in todays hitech. You have to pay for accuracy. Choose the car reading and feel happier 'cos it's 2 degrees higher.
