I use the first coat as a tack coat and no full coverage on the first coat is not needed and it can lead to issues if you force yourself to apply it that way. That's why the instructions on the can say 3-4 coats to cover.
I agree about no single stage for a beginner because you have to know where to start from and where your wet edge is and so forth.
For those who want a really fast out of dust clear it can be ordered by Oreilly's and its part number TRS 7761-MTR and its $103.99 a gallon. Its made by Transtar and its out of dust in 10 minutes and dry in 2 hours.
