I shut my bonnet properly every single time and always did the old lift to make sure it didn't come back up.
Then one day on an A road at 60mph...........
New bonnet, windscreen and roof work required.
After that I started the WD-40 and copper grease religiously.
And that was back in 2004 so long before Watchdog got a hold of it!
I knew I had something to do today...thanks for the reminderwee blob of copper grease and a squirt of WD40 fixes the problem
