I prepped the pieces in the usual way; soaking them in a dish of water with a couple drops of dish-soap added and then rinsing and drying. I then assembled the raft, by gluing in the oars and the fish basket, using Gorilla Super Glue Gel. (It also comes with a pair of loose fish, but I thought I'd save those to use somewhere else.) After that, I glued 1"x1" steel bases to the undersides of both models using Gorilla Super Glue Gel.
When the raft had dried for a bit, I gave the whole thing a wash with Citadel "Agrax Earthsahde" wash. Then, when the wash was dry, I drybrushed the bark with a 50-50 mix of Americana "Neutral Grey" and Americana "Mississippi Mud", followed by a lighter drybrush with Americana "Dove Grey". I then drybrushed the ends of the logs with Americana "Antique White", and the ropes with Americana "Bleached Sand".
