When I was satisfied with my light toned hi lites I sprayed the sculpture with Krylon clear matt to protect my work. Next I mixed a grayish green color and dry brushed that over over the entire brontosaur.
After another coat of clear Krylon matt spray it was time to give the brontosaur sculpture a wash of thinned down acrylic paints. The wash would help tie the dry brushing work together and accent the scale texture.
When the wash had dried I top coated the brontosaur with Kylon clear matt followed by a light misting of Testors Dull Cote. This left the sculpture with a slight sheen like the brontosaur was still a bit wet after emerging from the swamp to chase the sailors from the rescue party.
