I recently purchased an acrylic smoked sun visor for my new connect L230 but fitting it is turning into a nightmare, the visor is manufactured by V3PRO OY in Finland. The holding brackets are screwed to the window pillars with four self tapping screws on either side. I marked out the positions as per fitting instructions and commenced drilling the 4mm holes, drilling the body panel is easy but then maybe 10mm below that I have hit a 2nd skin and no way can I drill this, I have tried umpteen drill bits, cutting compounds etc so I now have four holes in my pillar skin covered in duck tape til I solve the issues. Anyone have any ideas what lies beneath?
