Found a Scratch

[COOPS]

Absolutely gutted!
Found a 3 inch hairline scratch on my car door this morning, think it has only gone through the lacquer. Can anyone give some useful hints on best way to deal with it. The paint is reflex so assume can not use T-Cut.
Thanks
Glenn

3M Finesse-it is the best thing I have ever used for removing scratches. Works well on our black TT. This was recommended to me by a Porsche/Audi/Saab bodyshop. Bought it from a decent independent motorfactors.
