  • bumpers

    Hi all,ive had my vxr for bout a week now and have noticed that the bumpers look a different shade to the rest of the car,i dont know if its just me but at different angles it changes.I have had a look at other arden blue motors on the pic section and i think they have the same problem.Is there anybody with any views on this. :?

    Hi there it is a problem of paint on plastic versus paint on metal.
    there is a thread somewhere on the site that covers it.

        yeah you'd have thought so but we still bought them anyway so why should they bother hey??? I think that is vauxhall's attitude.

          It's not just a Vauxhall problem it's a texture problem.
          I don't know what the answer is other than ignore it or get it coloured by a specialist
          Enjoy the ride by the way

                  --------------------------------------------------------------------------------

                  I hope his helps I have taken some extracts from Wikipedia.
                  Metamerism:
                  materials that are metameric color matches rather than spectral color matches, is a significant problem in industries where color matching or color tolerances are important. A classic example is in automobiles: paints may be manufactured to provide a good color match under a standard light source (such as the sun), but the matches can disappear under different light sources (fluorescent sodium or halide lights). This is due to the different light frequencies of streetlighting than that of natural light. Paints manufactured with brighteners are especially susceptible to color changes when lights differ in their short wavelength radiation, which can cause some paints to fluoresce.

                  Color matches made in the paint industry are often aimed at achieving a true spectral color match, as well as a tristimulus (metameric) color match. A typical spectral color match attempts to give two colors the same spectral reflectance characteristic, making them a good metameric match with a low degree of metamerism, and thereby reducing the resulting color matches sensitivity to changes under differing light sources. Colours seen to be true in daylight are often markedly different under orange streetlighting. This is due to the differnt light frequencies. The obvious place to see examles of this effect is at your local secand hand car lot. Where wings and doors that have had repairs are often obvious under the lot floodlighting. When seen in the natural light of the sun they often look OK
