It's easy to seal the primer by dropping a bit of laquer on it and watch
capillary action move the laquer around the primer next to the case. This
is how the arsenals seal primers.
Bullets are something else. Although normal bullet seating in case mouths
appears to make a water-tight seal, it doesn't all the time. Arsenals use
an asphaltum similar to road tar to seal bullets in case mouths. Case
mouths are sized a couple thousandths larger than bullet diameter, then
coated with wet asphaltum. The bullets are then seated and the asphaltum
dries sealing out water, air and other powder/primer-destroying stuff.
Sealing bullets in case mouths might be difficult to do in one's home.
Reader's may have a solution they'll share. I wouldn't want to try it
