Why does it look like this..??

Too much paint at once, not enough time between coats.

How long between primer and color? Hours, days weeks?

If you wait too long before color and it needs more primer before color.

Hmmm.. Maybe. I waited about an hour after primer before top coat.
And I did 2, quick light coats then a 3rd, "wet" coat... but even then it was pretty quick as it's a small area.. Around 10 min between top coats.... but I'm no paint guy, so you're probably right..something went wrong.
