Sure. But I spray a coat of 2k over the poly to fill in the scratches and then wet sand the 2k 400-600. No scratches to worry about cancelling out, then epoxy seal over that.
I doesn’t say anywhere poly is primed 400-600. Those are wet sanding grits and I would not be wet sanding poly primer.I'm confused by this reply ^^^ .............if a person has sanded the polyester with 400-600, why would they need to spray 2k over the already sanded polyester to sand the 2k with 400-600?

Whether it’s urethane or poly, I block at 220 then always spray a coat of urethane to help fill in the scratches, and wet sand the urethane.
Polyester primer is basically thin sprayable bondo, it will absorb moisture. Do you wet sand filler?
a different product from those currently marketed.
There you go!Wet sandable and waterproof2)
