Primer naturally has a surface that covers the substrate's unevenness of color, but also preps for paint by creating a even textured "tack."
But we all are spraying, and the Duster coat/s provide the "tack". That so, we want as smooth and texture-less start as possible.
If Kilz is applied by spraying, and is done correctly, only the 1st coat needs a little sanding. The second coat can go on a "bit" heavier, but between the two sprayed coats, there is less than 20% the "Thickness" of a single Rolled Coat.
If Primer is rolled on...absolutely....you sand each coat until slippery smooth, then apply Dusters to create the "tack"
Extremely important to both realize and remember is that S-I-L-V-E-R's ability to render exquisite detail, and enhance contrast and colors, also means it's terribly unforgiving of any Blemish, crack, smudge, or drop of Coffee that is on the Screen. Ridges become prominent lines. Dents become small versions of Moon craters.
Basically, you want as perfect a surface as you can find/get/start out with, or if necessary, make.
