skin problem

I recently made a skin for the 89 pessima. It all works apart from the black trim around the doors which spoils it. Is there a way to get rid of it?

 

Take a look at how the bodycoloured trim skin works.

Code:

singleton Material("pessima.skin.bodycolored")
{
    mapTo = "pessima.skin.bodycolored";
    diffuseMap[2] = "vehicles/pessima/pessima_c_alt.dds";
    specularMap[2] = "vehicles/pessima/pessima_s_alt.dds";
    normalMap[2] = "vehicles/pessima/pessima_n.dds";
    diffuseMap[1] = "vehicles/pessima/pessima_d_alt.dds";
    specularMap[1] = "vehicles/pessima/pessima_s_alt.dds";
    normalMap[1] = "vehicles/pessima/pessima_n.dds";
    diffuseMap[0] = "vehicles/common/null.dds";
    specularMap[0] = "vehicles/pessima/pessima_s_alt.dds";
    normalMap[0] = "vehicles/pessima/pessima_n.dds";
    specularPower[0] = "128";
    pixelSpecular[0] = "1";
    specularPower[1] = "32";
    pixelSpecular[1] = "1";
    specularPower[2] = "128";
    pixelSpecular[2] = "1";
    diffuseColor[0] = "1 1 1 1";
    diffuseColor[1] = "1 1 1 1";
    diffuseColor[2] = "1 1 1 1";
    useAnisotropic[0] = "1";
    useAnisotropic[1] = "1";
    useAnisotropic[2] = "1";
    castShadows = "1";
    translucent = "1";
    translucentBlendOp = "None";
    alphaTest = "0";
    alphaRef = "0";
    dynamicCubemap = true;
    instanceDiffuse[2] = true;
    materialTag0 = "beamng"; materialTag1 = "vehicle";
};

EDIT: Maybe I misunderstood... You mean the bit around the windows?
