Thanks guys, some good ideas, I'll have to give them a go
I always find the way the mist and dew on these cold mornings just keeps coming back on until the window had heated up a bit and I find I'm using the wipers for a mile or so down the road. I imagine that it's good for rain but the beading up of mist and drizzle etc very distracting. This is on my new tintop and, I guess, put there by the dealers as part of the valet it gets.
Cheers
Ivan
