Thanks guys. Geo, I've not yet done an oil wash like some do, whereby they coat the entire model and then wipe it down. I'm a bit more selective in my approach and dab it directly in the panel lines I want to highlight and let it wick along the recess. As for materials, yes, it was a trial and error process for me and I've had a couple of "episodes" when I tried this with a wash made of lacquer thinner and oils. This stuff is too hot and will eat paint and leave a white blotch. Then I tried acrylics with water cut with dish soap but I find the acrylics dry funny and leave a dark line at the edges. I've now settled on mineral spirits and artist's oils which work nicely and have some far not reacted with Future or other acrylic finishes and almost certainly will be fine with enamels.
Regarding the aluminum foil tape, I don't remember where I got it but the stuff looks like this and should be available at any hardware or big box store. It's used for sealing furnace ducts and should not be confused with everyday "duct tape".
As for progress on the model, I'm getting down to the short strokes now and offer up the following shots. First off, I sprayed on the fairly heavy exhaust staining that is evident in photos. I started with a gray/brown mix holding the airbrush close to the model near the exhaust outlets and moving it farther away as I moved toward the back. Practiced on a sheet of paper before I tried this because this would be the wrong point to mess things up! After the gray/brown mix, I went over it again with black but staying within the brown edges.
Here are the resin Quickboost exhaust stacks all painted up and ready to be installed:
Once again studying a reference pic, it appears that there was a patch applied over the external power receptical on the fuselage cross so I just painted this spot in a reddish brown.
The rest of the pics show the finished tail section, the Eduard replacement tail wheel, and the prop.
Hope to get more done today. Hangover's not that bad!
