once again the rear wiper

Hello municipality, I have dared to ask this forum how I can get used to the dusky tail wiper to wipe the top and bottom of the disc. The problem is probably the same as with the great black foil, only that it is wiped from the inside…;-). But now in the first place: from bending the wiper arm to installing a shortened spring until I bought an original wiper, I have tried everything. Since someone might have another one. Tip? What about these new “full rubber wipers”, which I have seen many times on the Wolfsburgers. I’m surprised that your wipers all work so well, just don’t hold mine;-(
