Hi, wanted to announce me once again briefly with long term test:
After I drove now summers and winters with the change, I can say everything in order in the winter warmly in the summer coldly.
Only one the Paint which I used, has at extreme temperatures (summer, car in the sun, estimated 70°C) blisters thrown. And I got some small tears.
There one should be a little more careful possibly with the installation.
I will make in the next days times a few pictures of the finished project. (On my side, see below)
