Scrathed me facia after pulling out stereo

[koonl]

I pulled my stereo out to see if I can get to a live wire to tap my Snooper into. After chickening out putting it back, I realise I scratched the front facia just below the stereo housing. I guess the rear bottom corner of the stereo scratched it as it was hanging vertically down.

Without having to spend £21 inc VAT for a replacement (quite reasonable I thought from Audi), I was wondering if anyone knows a way of hiding these blemishes. The facia is black, though on close-up it has speckles of blue in it.

thanks all
