Coming back, I built a hood and the front bumper.
Base coat was brown, then between spackling and dry brushing, added shades of red, orange and different brown shades.
Once this was dried, i used a brush and added some hairspray, sprinkling sea salt on this, I let cure over night.
I mixed water with a couple drops of dish soap, added a splasof of iso (alcohol) with the brush, I started (dry) rubbing off all the salt, then switiching between damp brush and dry cloth I rubbed off the paint, leaving the 'rust' coat behind.
Final touches added;
Blood, weathering and touched up the rust.
I am that which lurks.
