I have a mark on my astra (silver) which is visable in direct sunlight, its like when you get a branch/twig scratch on your paintwork or when a kid pushes his bike into the side of your car, but i cannot seem to get it out (its not deep and has not damaged the paint underneath by the looks).
What is recommended to remove/repair a light mark like this please?

I used the polish sold by polishedbliss in their intermediate kit to polish out a branch scratch on the scoob when I reversed into a bush.

Worked a treat, by hand.

 

On subaru paint I used menz 203s and a CCS light cut pad by hand to remove bird dropping etching and scratches, not sure of the level of hardness vauxhall paint is though

As above, Menzerna 203S applied using a Lake Country German CCS Light Cut Pad should do the trick nicely. Details here...
