Sealing bolsters and finger guards.

I'm getting ready to make my first bolster knife. I will use 416SS for the bolster and non-stainless steel such as A2, D2, or 3V for the blade. Do I need to apply some kind of sealer (glue) to keep moisture out of the bolster joint to prevent rusting? Also, I have several A2 knives with SS finger guards and rust is showing on the spine/finger guard joint where the gap was too tight for solder to penetrate. Any suggestions for this problem?
 
No sealer needed. They just need to be tight. Keep them clean and a little oil on them and you should be fine.

John,
Thanks for your reply. When installing bolsters, do the mating surfaces of the knife and bolster need to be polished or is a 220 grit finish OK?
