hey Oz1998;
well I use regular lacaur thinner for Humbrol, but another great paint is Aero Masters they have the correct color match for WWII paints, also Polly Scale/Floquil are great paints too, Testors has a very good color match but I'd hit on the Aero Masters or Polly Scale for acrylic or Floquil for Lacaur, then Testors,
As for effect I'd use Polly S's Oily Black, Grimey Black, Rust, and Tamiya's clear red(thinned) for the paint and a gum eraser for scuffing, and alot of extra time and it'll come out outstanding trust me
and remember to relax and have fun
