I spent some time yesterday researching and learning techniques for weathering ships. I don't claim to know a lot about this yet, and I am sure to make some mistakes, but what I did learn looks fairly easy enough to do. The trick of course is doing it in a manner that is subtle, relatively correct, and doesn't paint me into a corner.
I was originally thinking of doing some lightened base coats in a similar manner that I use on aircraft, and I may still do this on the deck. But the hull bottom and sides seem to call out for a different approach using mainly filters, washes, and various forms of streaking. So this is the approach I am going to use initially, and then evaluate it afterwards.
To address the desire to be able to back out, I will be using oils which can easily be removed as long as they have not yet been over coated. The photos I have of the ship show a splotchiness on the hull which I am not sure I can replicate using these techniques, but the rusting and salt spray techniques look effective in the tutorials. So we'll see.
First up however was to get the decals on. I had already gloss coated most of the model so it was simply a matter of adding the hull numbers and the name on the stern. Unfortunately, the white stern lettering was not provided as a decal. But the decal sheet had the name of the ship printed in black at the bottom edge (to identify the decal sheet) and the lettering appeared to be more or less correct in size and font, if not in color.
So I used a white marker and lightly traced over theses black letters, then sprayed over this part of the decal sheet with a decal fixative. I was able to successfully use that for lettering on the stern. The lettering looks a bit rough when viewed up close, but at a normal viewing distance looks fine.
This is the second time I have had to find some sort of solution for small white lettering. I wish I could find a more accurate means of doing this.
Anyway, the decals were gloss coated and I will be starting the weathering process later today.
