Hello,
Is it maybe possible to add some inperfections (dirt) on textures?
If they look perfectly new, it looks a bit unrealistic.
Or is that something I should postproduct alter in photoshop?
At present, there is no one click way to add inperfections (dirt) effects. You can manually add height maps with dirty and old effects in the texture parameters, simulating effects such as metal scraping and building wind erosion.

Hi! I think you can use the decals to create some old look materials.
Also, you can import old effects textures to achieve the effect you want.

You can add an imperfections image to the AO slot for metals. Anything without a defined texture in the materials will work with this. I got an imperfections pack from DGruwier at Gumroad. You would have to invert the imperfections image. AO goes to 1. Below shows a before and after of Mirror Stainless Steel. You can try it with wood too I suppose.
