Guaranteed, you will get halos around each sand-thru after spaying sealer.

Which leaves you with a couple of options, sand the sealer (if it's one that CAN be sanded) or, spray your base on top, sand that and then spray a final coat of base.

Some sealers (and some epoxies) are not sandable. I use a reduced epoxy (that is sandable) for a sealer.

I just thought of the possibility you are using ss (that you don't intend to color sand) and not bc/cc.
If that's the case, I would shoot a coat of sandable epoxy, block it with 400, then shoot another coat of reduced epoxy as a sealer before your topcoat.

I'm not saying that's the only way to do it. But, it's what I would do.
