Another post showing bits and pieces.
A scratch-built gas container made from some spare plastic tubes, detailed with sticky-back plastic and some plastic rod. A plastic bucket from the Italeri 1:35th scale Field Set, and a galvanised metal bucket made from rolled-up aluminium tin foil (a tin food tray). The final piece is a section of retail dispenser, used for holding small pots of paint. I have cut it to size and added some holes before painting it in my usual rust colours.
Four pieces of scrap plastic found in my 'bits box'. Bits from an old transistor radio, another piece of the small paint pot dispenser, scrap plastic and a mounting plate for a toilet seat. All painted with a basecoat of Vallejo Game Color Charred Brown/Hot Orange mix.
Strips of scrap wood, cut into planks or strips. They have been painted by adding a dilute wash over the whole surface and then painted with acrylics. I got the worn effect by using masking tape to remove some of the paint by pressing a strip of tape onto the freshly painted wood and peeling it off to give a realistic peeling paint effect.
