If you don't want to spend money on a new valence then why not cover the damage with black Plastic Paint (Gloss or Matt). A few members on here have painted theirs gloss black and looks quite good.

 

Good idea rjc, thanks for that. I'll have a search on, i guess i'd need some special tough paint as the area is prone to damage anyway, and will possibly need to repel some heat from the exhaust. I think I will get some light wire wool and try and 'buff' the marks out. Looking in the cold light of day the cuts aren't deep at all. I'd need to do this anyway if I painted it I think, and if it looks awful then i'll try and find the elusive OEM part card for a factory valance. I'll take some before and after pics with the wire wool.

 

If your going replace it get a Sprint one http://www.ebay.co.uk/itm/Genuine-Alfa-Romeo-Giulietta-Rear-Diffuser-50903312-/321315764260

But don't pay that price if you wait they often come up at half that from Alfa dealers.

 

When I bought a twin outlet one last year it cost £55 so they aren't hyper-expensive. You could try a breaker too? If you need a trim for the exhaust pipe itself I have a standard one - it only pop-rivets on the end of the pipe.

 

Maybe these?

These are from a dealer that I have used for alloy wheels and they have been very good!

 

There's a few available from alfisti.net

Alfa Romeo Giulietta Tuning & Styling - Stoßstangen, Spoiler, Schweller und Bodykits - Alfa Romeo Shop - Tuning, Styling, Fanartikel und Modellautos

 

I can't say I like the look of the sprint diffuser
The Factory Diesel dual valance is alot cheaper than any of those options:
Diffusor With Left/Right-Sided Exhaust Port For 1.4 TB / 1.6 JTDM - Alfa Romeo Shop - Tuning, Styling, Fanartikel und Modellautos

65 Euro.
If your car is Petrol and single pipe, I'd guess the standard single pipe version is a similar price from your local dealer.

 

Like for like on a single outlet £61 odd:

The material used is for the valance is likely to be high density polypropylene which will be extended with talc content and moulded with a grain. It's unlikely you'll ever be happy with the results !

 

Thanks everyone very much , and especially andypj. I bow to your searching skills ! The £62 shop4parts one seems pretty decent, looks like they only become silly money if you go for something a bit flash. :thumbup:

 

I had a damaged one when I got my g. My fix was some carbon look vinal wrap. It's a £5 fix and even if it doesn't last long, I'll just re do. All you need is to take it off, clean it up, a sharp blade, hair drier and an hour or so of time.
