The bright colours of yesterday's base coats of paint quickly muted as Peter brushed on and judiciously wiped off the glazes. The textures and crevices were enhanced by the transparent paint left behind. The plaster suddenly looked old. Once the glazes were dry Peter then added the highlights and further aged the pieces using a dry brush technique. The last step was done by using the sanding disk in the grinder to deliberately remove paint from the freshly painted metal. Each pass was carefully planned to appear haphazard. A little sprayed acid aged the metal by years in a few minutes.
