The effect you describe is called "hatbanding".

At least I know what to call it.

1. Streaking indicates insufficient coverage. Use a wider brush and
load it heavier. I like a 2"-4" sash brush. Sash brushes tend to
have a tapered end which feathers out better than a blunt end,
letting you control the edge better. After you put the paint on,
drag the very end of the hairs very lightly through the paint.
This is called "tipping off".

As I said earlier in my post, SEVERAL COATS above and beyond the rest
of the wall and I still have the effect. I'm slobbering on as much
paint as will stick without running.

Dragging the end of the brush lightly through the paint only
accentuates the problem. Leaves streaks.

Oh. We have a terminology conflict. What you're calling streaks are
actually brush marks. Streaks means (to me) that you can still see the
old color through the paint. If brush marks don't go away, your paint
is too thick. You can thin it a bit (_only_ a bit), or you can add
Floetrol (Penetrol for oil paint). Floetrol increases the surface
tension, thins the paint, and slows down the drying so the paint lies
down flatter, hiding the brush marks.

2. Run the the roller horizontally as close to the corner as you
can get it without putting paint on the ceiling. Make sure you
have plenty of paint on the roller. With practice and a good
roller cover, you can get within 1/4" of the corner.

Even at 1/4" I still get the effect, and painting that close I'm too
much of a spaz to keep from getting paint on the adjoining wall or
ceiling.

Well, a thinner paint will help some, but there's no way to completely
eliminate the hatbanding without using the same device to apply the
entire surface, whether it's a brush, a roller, or a sprayer.
