Mckellar's photo above does not do it any justice, it makes it look as though it stands out and could be seen from a mile off even though its black!!
Believe me, its hardly noticeable. When in Halfords (not rome
) check through the packets on the shelf. I originally bought some for my polo which were quite low and flat, I went back up, purchased some more and the one needed was about half a centimetre thick. It looked wank!
I went back up and bought another packet and luckily ended up with another thin one.
I am so glad I've done it, makes the back look much much smarter. Will get some photo's of the back of mine up later.
The other thing was... smoothing the rear wiper, unless you remove the rear window you will end up with a **** job. The paint can only be blown up so far and when masked off will leave a sharp line.....
