Diffuser refurb help?

Iv just taken off my diffuser and im really pissed off, because iv taken a little chunk out of it where it clips in. The chunk is only about 1-2 mm but its visable and really irritating me.

Any idea how i can get rid of it?
 
You got any photos of it mate? If its so small I wouldn't worry too much but for a quick fix it would be filler and either paint or a marker but it really depends on what the damage is like....
 
To be totally honest with you its not really that noticable, but im quite fussy with the car since im trying to go for looks and not performance with it.

I was thinkin about wet and dry but the problem with that would be it would leave it rather smooth and the diffuser isnt smooth is it? lol

I havnt got any pictures of it mate, but seriously its only like 2mm so nothing major, just wondering if there was a quick fix.

Paint? what kind of paint to match it?
