A few kilograms of putty on the car door

To find out the maximum recommended layer of putty should carefully read the instructions on the bank. The masters in the video do not reckon with the manufacturer's recommendations, although the first layer was still applied with fiberglass, as it should. One can only guess for what purpose this repair was made, but such a thick layer is held on, especially on the car door, it will not be at all long.

From the joyful cries of car mechanics in the video, it is clear that even they did not see such layers.
