| when i built my jules verne nautilus sub, i brushed on rust powder, i then used a plant mister/ sprayer and every 3 or 4 days gave it a mist of salt water, this ensured the rust ' keyed' onto the surface as it was there for some time.... after about 5 weeks the effect was ideal, and excatly what i wanted...... no need for spray mount as the rust started to key into the paint finish.....
