Thank you guys,
Next job are the rudders.
I removed the welds because they are not correct, i will replace them later with welds from the Archer kit.
On pictures from the 995, i noticed the rudders also have a rough steel surface with small holes and dimples, so i had the idea to simulate this with the help of some plastic cement and a piece of a steelwire brush.
On this picture the surface with the small holes clearly can be seen.

The parts needed to replicate the steel surface
I brushed on a thin layer of cement to soften the plastic, after one minute i added a second layer and immediately started to push the wirebrush into the surface to create the holes.
After one hour of drying, i sanded the surface smooth to remove the small pieces of melted plastic, and only the holes remained.
I am happy with the result of this wirebrush/cement experiment
