Painting tips

A little help, I picked up some QRF not marines and not aliens at Cold
Wars,
now it is time to paint.  I tend to spray prime in the base color,
probably
khaki for the marines, but I'm open to suggestions for the bugs.  I want
to
see the details, but paint them fast.  BTW I can dry brush, I just don't
as
a rule.  I also use the 3 foot rule in painting, if I can't see it at 3
feet, I really don't need to paint it :-).



Thanks



Mike
