Paintwork Abnormality

[drewbie]

Hi
My 75 is finished in Starlight Silver and on the horizontal panels, bonnet, roof and boot lid, as developed what looks like hundreds of tiny scratches and is slowly getting worse. It looks awful when the sun catches it at the right angle. No scratch remover produce or nano clothes have any effect, in fact you cant even feel what looks like the scratches with a finger nail, it's as if the colour or clear coat is breaking down under the surface.
As anyone else experienced this with their paintwork and possibly found at least a method of masking it.
