Just a little imformation on the whole concrete colour saga,I was in my local model shop yesterday and thouoght I should check to see if you can indeed still get #95 and wouldn't you know it humbrol don't make it anymore.However it's not all bad news as humrol have published a booklet showing how to mix it ourselves so I copied the recipie down and here it is.
28 parts #103
34 parts #17
1 part #101
with a bit of weathering it looks pretty good
hope this helps some one
cheers Dave.
