I received the 1:35 GMC M12 for Christmas. Looks great but reading through the instructions I'm totally confused about paint. The box lists 9 colours while the instructions list just 3, of which I can see only 2 actually shown as being applied. These are Humbrol 155 and 173. I can't see where Humbrol 53 is applied let alone the other 6 colours listed on the box!! It's all a bit confusing. Can anyone help make sense of this for me? Take care David
