Ah! You've used the top half of the Union Jack.
Smart move. Looks like a very credible solution to the problem of foreshortening.
I had a bit of time to look again at the spoiler on my convertible and I came to the conclusion that the underside of the spoiler looks untidy (my car is Rhodium Silver also) because of the fiddly contrasting areas like the lift bracket, and buffer screws etc..., so i'm planning to get the underside surfaces sprayed in satin/mat black prior to adding any graphic to the underside surface.
I think it will look cleaner, sharper and give the decal more definition.
Nice one Bri
.......at the scale that you have mage it, i'm now wondering if the faded/weathered Union Jack will look more fun.....what do you think?
