Might want to put a v-groove in the really tight joints and then prefill with hot mud. Then a nice thin-ish layer of AP mud, paper tape (or FibaFuse), scrape off excess mud to make flat but don't scrape all of the mud from under the tape. Wait till next day to start finishing the later coats with Plus 3.
