I've spent many times in eBay and Aliexpress to find out a sunshade for the glass roof but I did not find anything suitable for SLK.
Many people use film instead of the sunshade, but there were many complained of peeling off.
I also don't like films because it made poor visibility (to the beautiful sky) at night
. So, I decided to create my own sunshade.
First, I've ordered a sunshade which is larger than the glass roof (80x30 cm) then cut into the glass roof size.
Then, sewed the rim back to the edge of the cut piece. Finally, cut the wire and fit it back.
In my opinion, it works better than films and costs me just a few dollars and 2 hours.
Hope this helps someone driving in too much sunshine city
