W mojej relacji z budowy Emmonsa, Piotr d podlinkował mi instrukcję malowania okrętów USN z 1943 r. https://www.shipcamouflage.com/painting_and_cementing_toc.htm. Jest tam też rozdział opisujący malowanie podwodnej części, w tym oczywiście wałów https://www.shipcamouflage.com/painting_and_cementing_chapter3.htm#Chapter%203.%20-%20Steel%20Construction%20-%C2%A0%20Underwater%20Body
SHAFTING.
Outboard protection. - To avoid shaft fracture due to corrosion fatigue, it is necessary that pitting be prevented. In order to insure this, all outboard shafting shall be carefully sand- or grit-blasted prior to painting.
Immediately after blasting, one coat of zinc-chromate primer, formula 84 or formula 84D, shall be applied whether the shaft is blasted after installation or in the shop.
Prior to launching or undocking, apply an additional coat of zinc-chromate primer. Allow eight hours to dry and apply one coat of anti-corrosive paint, formula 14 or formula 14D. Allow four hours to dry, then apply one coat of hot or cold plastic anti-fouling paint.
All parts of shafting which are inaccessible for painting and not protected by bearing sleeves of metallic casings shall be covered by rubber or by other specially approved materials.
The Bureau may specify special coatings for the accessible portions of steel shafts of wooden craft to minimize corrosion.
Inboard Protection. - Inboard sections of propulsion shafting shall receive two coats of zinc-chromate primer, formula 84, and one coat of light gray machinery enamel, formula 30-L.
