Hello, in March comes our new XC90. This time in silver-metallic. Since I did not want to do without the VSG (noise insulation) I now look for a possibility to sound the discs afterwards. Question: Does anyone have experience with subsequent tint of VSG discs? I have concerns, since the laminated glass panes are already very thick and I fear that the panes with the additional foil in the rubber seal of the rear doors clamp or quickly blur.
