Guys Im so annoyed!!!!
I spent hours preping and painting my spoiler only to find Halfords colour match is way off. The guy mixed the nocturno blue from the paint code I got from the inside of my door. Although it didn't appear in the system under Vauxhall but Opel. However I can't see why that would matter. I did expect a slight difference as its impossible to 100% match, but this is more of a 65% to 75% match.
I'm so pissed off.
