I got some Behr high-gloss latex enamel with which to paint some trim.

Using a Peavy brush, roller, or foam applicator all yield god-awful results.
Specifically, in the case of the two brushes, the paint looks like it was
applied with a fork. Using a roller, the result looks like an alligator
hide.

The application was on top of a Behr primer.

Any ideas on how to use this paint to yield an acceptable finish?

Thanks.

Failing expert advice, I'm gonna take a bit of trim with the aforementioned
application techniques back to the paint store and accuse them of selling an
anti-barnacle, boat-bottom treatment instead of paint.
