What Nason Paint Primer Actually Does Before Topcoat
This flow additive may be used in new nason single stage topcoats to help improve flow, leveling, and overspray absorption in hot weather conditions or when spraying large vehicles. When modified as a sealer, it is easily applied, offers good holdout and lays down smooth for excellent topcoat appearance. Discussion among autobody enthusiasts, anyone wanting to become more aware of processes and what it takes to fix automobiles. Just cause you saw it on youtube doesn't mean its the right way to do it. For my personal old vintage cars i would usually use the nason 2k primer with dupont chroma base top/clear coat.
If your goal is to have the bottom look as good as the top, you need to apply high build primer and sand it smooth. Since 'life got in the way', you do need to scuff the epoxy primer for mechanical adhesion.
