All of the shots are actually natural light/a spotlight we found in the hangar. I never use flash. I think what it comes down to is not having a polarized filter and wrong angles with the spotlight.
And for those guys wanting shoots done for your cars, in the original post there's a link to my facebook photo page. Just message me on there (because on here it gets too confusing, and it's good to have it all in one place) and we can figure something out!
