Its been happening for that last few months on and off, but last night in tesco's carpark as I was getting out of the car it was more fierce. My arm stung for ages, glad I had my coat on.
Then as I pulled up outside the house, it didn't do it but it did spark between the car lock and key... it was a blue/white spark and a big one at that.
And today its been mild again, but I'm getting fed up by getting zapped everytime I get out the car.
Whats causing it?
Is it an earth strap?
