HELP/Mrs Woos Car

Don't bother - absolute waste of money to be honest; been there, done that and almost wrecked a bonnet with the stuff.

You can get metallic T-cut which would be more appropriate, however I would be inclined to go with Autoglym Super Resin Polish to start with - - start on the scratch in small circular motions, and then you can buff the whole car up, and get even more brown(ie) owl points It looks to me from your pictures that the scratch hasn't even gone all the way through the clear coat, let alone any where near the coloured layers, so all you want to do is essentially flatten the contours of the scratch out a bit, and then fill it with optical fillers, which is exactly what Super Resin polish will do.

If you want an extra special finish, treat yourself to a Halfords mains powered buffing machine and some lambswool mitts; you could even go for the Extra Gloss Protection from Autoglym too.
