Thanks for the kind words! I’m no weathering expert but I like the way most of it turned out. To do the floor, I sprayed the sheet styrene with grey primer from the hardware store, then brushed a darker weathering powder over it. I then would drop a small puddle of black and brown tinted thinner and spread it with a brush. It mixes with the powder and makes great “dried up” fluid stains. Who knows if that’s the best way, but I like it and it was fun ?
