Glad you got it sorted mate. I know only too well how bad it can be when a bonnet pops up at speed.
18 months ago I had the scoob in for a respray on the bumper. I didn't know at the time but they had popped the bonnet looking for the paint code and not shut it properly... Pulled onto a dual carriageway and as I was overtaking in the outside lane around "70ish" the bonnet came up - I hit the Armco, span 360 in front of the car I was passing, hit the curb, bounced up and was less than a foot from a 15m drop when I came to a stop. Suffice to say I was bloody lucky!
