Encouraged by the cupola lid, I decided to add some more detail texture to the turret front face, the mantlet and the MG ball cover on the front glacis plate. I took the technique for adding the texture from this link.

So i bought a couple of different size brushes and of course Mr. surfacer 500.
For detailing the areas mentioned I decided to use 2 methods for applying Mr Surfacer.

First, I cut regular dish washing foam to small square sections.

For large flat areas I used foam dipped in Mr. Surfacer and stippled it to the area I wanted to add texture to.

For narrow areas where the foam would be too broad, I used a brush instead
