Primers

Question for the paint gods.
Is it primer for block sanding before sealer or after? :-k

yep,primer is to be all sanded before sealing.one would use primer to build the substrate up and block it flat to get rid of any waves in said panel.sealer is applied before any color is applied.it's purpose is to provide one uniform color on the panel(s).that way you use the same amount of color across the board because your not going over diffrent colors on the panel.ie.spots of primer etc.i guess you could say the sealer provides color hold out for applying the basecoat.
