inked1974, the spray foam should seal the bars from moisture. Also it is an epoxy sort of material which does not readily absorb moisture.
Another way to dampen handlebars is to weight the last inch or 2 of the bar ends with lead shot or sand. The trick is to figure out a way to keep it there.
Another idea is to get yourself some mechanics gloves with the vibration absorbing palm padding/ gel. They are marketed for use with pneumatic tools to reduce the inherent vibration that die grinders, impact guns, and such transmit to your joints, tendons, ect.
