Your car looks really nice but the thing that really stands out as needing a bit of a spruce up is the front calipers. I did mine in-situ using some eBay caliper paint and a small paintbrush after carefully masking the obvious bits you don't want to get paint on. The paint on the logo can be removed easily enough with a Stanley blade and/or a sanding block. It would obviously have been better to remove the calipers, dismantle them and spray them but I think that they look fine the way I have done them.
