It looks great mate. You sound as if you're happy with the quality of the finish, which is the most important thing. IMO it's no so much the quote that is the deciding factor but how good the quality of their work is. Ovni is a thin paint (I'm no expert...) but I suppose the difference between a lighter and darker finish is a couple of extra coats? Would you have gone as far as Faisal did with his yellow?
Either way, I'd be really happy with your results, especially hearing of other's woes recently. Look forward to the pics.
James.
