This is my first post so be gentle :)

I took a standard Halo Reach Warthog added several layers of acrylic and dry brushing to give it that worn, weathered & Battledamaged look.
Nothing has been modified to the Jeep itself aside from some solder burns for blast effect, so largely only a custom paint job.
When I find the time I will try my hand at installing a lighting system for the spotlights etc... but for now thats out of my very small skillset.

I found Water based Acrylics the best for this job, watering teh paints down I was able to get some very effective windshield splatter and mud splatter.

Hope you enjoy!
