That's interesting, just haven't seen it in a long time, not that I have been looking for it! LOL! I went to urethane primer years ago and never looked back, lacquer has way too much shrink back for me. Having sand scratches reappear after paint is a real bummer.

I have a mess on the floor I can mop up, the dry sand has dust everywhere and covers everything. Just wanted to know what others do or have tried.
Oh, ok, I have never used Matrix, but I think you just have your names mixed up. I am going to guess its polyurethane, not polyester. I would definitely wet sand it before any top coat is applied, be that color or sealer. sealers are generally not sanded, but rather applied right before the top coat goes on.
