Thank, Hokey! Sure thing.
I used the Eduard PE for this kit (there are 3 sets). I considered Oto's brass deck but it wasn't ready in time, so I just used the kit deck. I also used a brass kit that has the screws, the UZO, the captsans and few other items.
I primed the kit with Tamiya Fine Primer. Then I preshaded all the rivet lines and panel lines. I used reversed pre-shading for below the waterline. After that I painted the sub with LifeColor paints. They have a Kriegsmarine set of paints that colors that I wanted to use.
I had a little trouble with the LifeColor paints, probably due to my inexperience. I had trouble figuring out how much to thin it. It would clog in my AB very easily. So I ended up thinning it quite a bit and layering on a lot of thin coats.
I then sealed it up with Future floor polish and started weathering it. I used Gamblin artist oils and odorless turpentine for all the washes and filters. I started with several dark washes of black and brown. I would then put down a dull cote to seal it. I used dot filtering above waterline. Below the waterline I applied some light grey filters to fade the base paint.
I was able to get some splotchy effects by diluting some white oil paint with lighter fluid and splattering that on the hull below the water line. The lighter fluid drys very quickly and leaves behind an irregularly shaped faded mark. I basically continued to apply different oil paints as I saw fit, and then started adding specific rust streaking on the conning tower and upper hull.
For the deck I used nato black and then painted areas of earth brown to make it look like the carbilinium had worn away.
After all that I did just a little bit of pastel weathering here and there. To age the screws, I soaked them in vinegar and salt for a few days.
That's about it. I started it in April and finished last week (October 3). I learned a lot. It was my first attempt at weathering something major.
Hope that helps!
