Big UpdateSo I finally got my spoiler back from the body shop, after taking it to one bodyshop who did a crap job (paint reacted), and I asked them to redo it, kept saying it would be done next week, next week, next week, kept discounting the price, and eventually said they would do it for free because I'd been waiting so long. Two months of waiting, one day the guy just says take it back, I don't have time to work on it. So I ended up taking it to a different bodyshop, who had it done in two days:

Bought some adhesive foam strip as well to replace the factory Honda ones:

Because my Boot roof has a different colour to the rest of the car, Premium White Pearl, instead of Orchid White Pearl (see first post for explanation), I didn't like the idea of the spoiler and boot roof being noticeably different colours, and I didn't want to pay to have it resprayed, so I had an idea.
Here you can see the colour difference, though I feel it looks more noticeable in real life:

Back in my younger days on the modified car scene late 2000's, the Honda Civic EK9 Type R was reaching the 10 year old mark, and didn't need an expensive SVA test to be imported into the UK from Japan, so they were starting to flood the market and appear at Japanese car meets. And most of them came in the lovely Championship White, which was always so beautiful, as White cars were rare back in 2007, (now white cars are absolutely everywhere), and you definitely couldn't get a white Honda! And the spoiler on the EK9 had a Matte Black base plate, and I always like the black and white contrast this gave. Like so:

So I bought some Matte Black Vinyl Wrap from Amazon for £6.99 and thought I would have a go at wrapping the boot roof.
I cut the vinyl down to size:

Then set about slowly and carefully applying it to the boot roof. I only used a heatgun and squeegee for the harder areas, everything else I just took my time and used my fingers to smooth it down onto the boot roof, which I felt made it a lot easier.

Then using a hobby knife I cut off the excess and folded it around, and the final result came out even better than I had hoped for!

Then all that was left was to fit the new spoiler:





I'm very happy with how it turned out, and I feel the 'look' of the car is finally complete.
Honda really should've included this spoiler with the Si as standard from the factory, as it just looks odd without it.
If you look at the Japanese Market Fit RS and Asian Market Jazz RS, they have the same kit as the UK Si, but they have the spoiler.

For now, this is all the outside modifications I want to do on the car. In a couple of weeks I will be stripping out the entire interior to lay down Silent Coat sound deadening to make the interior whisper quiet (hopefully).
After the success of the vinyl wrap on the boot roof, it's making me tempted to buy either some Matte Black or Gloss Carbon Fibre wrap and do the front bonnet. But I'm going to sit on that one and think about it.
For those of you who like the look of the spoiler and want to get one for your self. Go over to eBay.com (US eBay), and type in the search bar: 74900-TK6, and it should come up.
I was lucky enough to get one for £100 including shipping and import duty.
You can get copies from China/Taiwan, but I can't speak for their quality compared to the genuine article.
