Tamiya Weathering Master sets?

I can recommend the mud-stick and the oil-stain color. Nothing else is worth it, imho.

I would highly recommend them.You can get some really nice results once you get the hang of it.

This Horch was white-washed and muddied up with Tamiya kits.

This was dirtied up as well.

The scorch marks on this kit were courtesy of Tamiya.

Just a few examples of what you can do.I'm no expert,but I'm happy somebody around here recommended them to me.
