Just cleaned the car this morning and it's covered in tar spots from a 500mile round trip to Norfolk last week.
I've been noticing for a while that I have to remove more tar spots in winter than in summer. Iridium silver is a relatively easy colour to keep clean (I'm on my 8th Mercedes in that colour!) apart from the tar spots!
Most road surfacing work is carried out in the summer and the tar is softer in the warmer months so why does it choose my car to land on in the winter?
Is it more brittle and small chips break off more easily at lower temperatures? ...and if so, how does it manage to weld itself to my paint work:dk:

Can anyone explain one of life's great mysteries?

PS. Do you know why you are more likely to get a puncture when it is wet?
The water acts as a lubricant for sharp objects to pierce the tyre:doh: True!
 
It's global warming. That seems to be responsible for everything.
