One 10ml bottle of each color will be more than adequate for a 1/48 F4F.
Now like Don said above, if your doing a large aircraft say like a four engine bomber in a single color such as aluminum, the 23ml bottle is a good idea.
F is for FIRE, That burns down the whole town!
U is for URANIUM... BOMBS!
N is for NO SURVIVORS...
