I have the very same problem. Paintless repair is not possible due to the location of the small dent which is just above the central cross member
A proper repair job would see the whole bonnet painted and no doubt the wings etc to match...but if I were selling the car it could look like a whole front end respray...and if I was trying to hide something!

Didnt realise that a whole bonnet was as cheap

, its maybe an idea right enough, provided that the paint shop can effectively match my tornado red...(notoriously difficult I gather).

Or I just live with it and put up with the imperfection?
