After a good wash down with detergent to remove grease and stuff I lightly roughed up the surfaces with 800 wet and dry, ready to apply the milliput zimmerit. This was applied a section at a time and drawn out flat and smoothed off with a plastic scraper and lots of water.
The black milliput was where I ran out of yellow and had to blend in. The engine screens were flea bay purchased, very good and detailed but the mesh is very delicate and breaks very easily. When adding Milliput zimm, I find it best to press in tools and tow ropes when still soft, but remember to remove again before the putty sets if you want to paint them off the model.
After the first dusting of primer in readyness of pre shading.
