Here's a LINE-X Xtra black color match. Yep, lot's of different shades of black!
My line-x guy never mentioned it and I actually asked about color matching but backed off after hearing the differance in price. I don't remember him stying anything about a second coaing or fade resistan coating. This was July of '07.
And yes many many shades of all the colors. My generic Line-X black looks good on the Vista Blue
