How long do I let it dry for and wipe the excess off?
Morning Again Death of Blades…
When I do an artist’s-oil & turpentine wash (for tanks), I usually let it dry no more that a 5 minutes before rubbing off the excess with a Q-tip dipped in turpentine.
When I do an india-ink and alcohol wash (for aircraft), I do the wiping off almost instantly.
Just FYI, if you can find this month’s copy of Fine Scale Modeler (July 2008) there is a GREAT article on applying washes !! http://www.finescale.com
