John Willis and m Ransley,
Where did you learn the technique to use multiple coats of primer?
Primer's function is as a sealer and bonding coat. It is purposefully
thinner to soak in rather than sit on the surface. It seems to me that
once the surface is sealed there isn't much reason to seal it again.
At that point you want to start filling voids and adding durability and
color - in other words, the top coats.

Why use multiple coats of primer? To fill imperfections in the
surface. Primer is easier to sand and dries fast, thus multiple coats
are easy to put on, sand, and clean up.

One coat of primer will seal the surface, more or less. Multiple
coats, with light sanding and good cleaning between coats, will
provide a very smooth surface and give higher quality results in the
final finish.
