I bought this little grader off of EBay with intentions of weathering and re-selling but it looks so good on my diorama that I think it is a keeper.  This grader was weathered with sandpaper, chalks (alcohol used as bonding agent) and real dirt.  I even shot the windshield with my pin nailer to get realistic broken glass.

Finally got time to do some work on this project.  I plan on building more of these to sell later.  I Really like how this one is turning out.  I used Fisker crimpers and printed cardstock for corrugated metal.  Still need to weather and blend with chalks.

I picked up a couple of these brushes at Walmart for about a $1.30 apiece.  I dipped one in 50/50 green acrylic paint/water and left the other natural.  I cut random lengths with scissors and applied with my electric flyswatter static grass applicator.  Not too bad for a micro investment.

Logging camp tents I built for a client.  Scale is On30.

Slow progress but here are some current pics.
