So yesterday morning was cold, and therefore ideal for test run.
After 45 miles, three small instruments remained clear. The oil pressure gauge had very slight misting, but hardly anything.
The heater was on full, with occasional use of the fan.
More interesting is that my speedometer slightly misted over in the centre. So far I haven't drilled the two large gauges because they rarely mist up. When they have misted up, the four small gauges have been impossible to read. I therefore conclude that I have almost solved the misting.
Perhaps I may drill the large ones over winter. We'll see.
