Experienced auto and aircraft painters can tell you the woes of trying to match and patch a yellow vehicle. The inherent problems of dealing with yellow are exacerbated when the part is painted in-the-mold and produced off-shore.
It would require pages of text here to fully explain the reasons why and the techniques to overcome the problems. Government restrictions on certain components of the pigment add to the challenge.
While yellow is a most desirable Hi-Vis color for your model, please accept that there will sometimes be slight variances in the "tone" or "hue" of the color from part to part.
The BVM Ultra Bandit features the best "yellow" paint job in the ARF industry because we can completely control the process here in our Florida, USA factory.
