I don't know if this helps but I looked into getting my fiat stilo wrapped in chrome blue I got quoted £3,000 for a all over wrap door lining everything wrapped so no original colour to be seen,
Then another company quoted me £2,000 yet again all over wrap hiding the orginal colour
Another company quoted me £1,500
But just a outside so if I opened the door the original colour would be seen,
So I'd say shop around for quotes and see what you can get, I've orded some 4D black carbon fibre wrap off ebay today size being
1,520mm x 1,000mm being more then enough to do my bonnet cost me £13.99 should be coming Tuesday or Wednesday so I'm going to give it ago myself see how easy it is or hard and if it's easy enough I'm going to do my hole car in lime green wrap bar the bonnet and spoiler...
Anyways I can't see it being too hard as I'm good at DIY and angels and stuff so I should find it easy, if you would like I'll upload a photo after I've done it and tell you how it was? As I've never done anything like this before so I'm a complete noob so if I can do it anyone can!
P.s forgot to say chrome is the most expensive wrap so they charge a bomb for it... Even though the sheets on eBay are same price as the rest they seem to charge more for it...
