Josh,
That first would suggest a brick red undersides as a sort of antifouling but i am in no means an expert in modern subs and their colours. Maybe one of the other members would have a solution for you....? Ofcourse, putting in some effort and googling/ image googling the george washnington would give some result at least?
Hope you will find some answers soon as i eagerly await your progress pictures
As for my little (...) german WW2 sub i have promised you guys some update pics...:
As i have told you my acrylic undersides color (revell 77, dust grey) ran out so i put on a second coat with my last enamel number 77..... was juuuust barely enough (note from builder: if you buy this kit, expect to use a full bottle of paint on the undersides/ antifouling). After drying i proceeded with a lighter shade of (revell acrylic) grey on the upper hull.
The subsequent instructions told me to spray the deck in revell's number 69 granite grey. I chose to deviate from the instructions here as this shade was particularly greenish grey. I suppose this was to simulate some kind of algea growth on a worn deck.
Reading on the subject though i found out that the germans used to use a very dark (blackish) protective coat/ varnish on the wooden deck structures and recoating them after every patrol. Furthermore it is a fact that algea tend to make a deck rather slippery and hazardous for the crew to traverse during patrols so it would be highly unlikely for a uboat captain to allow such algea growth to accumulate during a given patrol. This coat would get a lighter shade as time progressed...
To simulate this kind of deck i have chosen to use my own mix of leather brown (wood colour) with a lighter brown and some medium grey to simulate the coated deck. After drying i used a black wash to accentuate the seams between the wooden slats on deck and leaving some of it on various parts of the deck as to simulate the coating to have not worn of fully yet.
After this i have drybrushed some of the non wood panels and hatches in a gunmetal (humbrol enamel) grey and after that a drybrushed a layer of revell's number 83 (enamel) to simulate worn old rust on the deck panels and hatches and also the various flood holes on the hull.
This (in my eyes) finishes the hull and deck for the subsequent weathering with lighter shades of rust and white for accentuating.
Next up will be the painting and finishing of the tower and its gun emplacements...
Hope you guys like my work sofar and i am always open for your suggestions ofcourse
