If you get the wrong color svx you might get the wrong color glass. The pearl paint in the case of an svx can be blended too. You're thinking about a 3 coat pearl (color coat, pearl coat, clear coat). Those are almost impossible to match because the pearl is it's own pearly clear coat and can be applied in different thicknesses. The SVX uses a 2 coat pearl (pearl color coat, clear coat). As long s you apply the color coat thick enough it will match, you can't apply it too thickly. Pearlies aren't that hard to find. I would just keep my eye on ebay and do a carfax on anything that comes up and looks interesting. Sometimes people on here are willing to go look at nearby cars if you ask too.
