I wonder who they use for what they mix. What I saw on the site was their own label. If it's SEM, PPG, Axalta (DuPont), BASF (brands off the top of my head) then it should be OK. I prefere PPG myself & have great experiance with thier products. But the main thing everyone has to keep in mind is recoloring or changing the color of parts to match the original will not be 100% even matching NOS parts protected from the elements & light. Even when new everything wasn't a perfect match due to dye lots, reformulations, different materials used for each part. Then add age/enviroment/weather/light to what you have now. Even how & what was used to clean (if ever cleaned) the interior parts will alter the shade over time. With the recolor, how long it has been since the color was mixed, the change in air temps from when the first piece to the last one was done, even how it is hung/placed (like flat on horses/stand, hanging it like it wound be mounted) will alter what the final apperance of the hue will be. But there are those with the right luck that it all is good. Best is black cause nobody notices unless it's too flat or glossy.
