Shellac, the near-universal sealant.

No idea what your making but could you make a small Shooting board to use with a block plane?

Beautiful finish, no sanding marks and very precise.

Have you tried a 'sanding sealer'? ie. Wattyl Sanding Sealer or similar.

Although (de-waxed) shellac or sanding sealer will seal the end grain, that might not really be what you're after. It sounds like you might have stepped from coarse to fine sanding a little soon, without an intermediate grade.

I also make scale models, with heaps of exposed end-grain, and have to sand very heavily with 220 after 100 before going finer or the 100G scratches will never disappear.

Try a nitro-cellulose sanding sealer, has good grain filling properties. I use it on spindle turned objects with large end grain areas.

I have been able to sand a smooth surface on a hardwood end grain by going up in grits. Not tried pine so not sure how it will behave?

I have read somewhere that you might be able to seal the end grain with diluted wood glue. You press it in with your thumb and wipe the excess off. I am not sure how it would look as I never tried it and might suggest a couple of test pieces.
