This subject seems to come up every now and then.

I wonder if anybody has come up with information about how to metalize
inside the via holes?

I am not a chemist so please keep any information suitable for a dummy.

I have tried silver paint but it is too viscous and it would need some
suction or pressure to give a smooth surface. Also it is most
important to me to be able to be left with a suitable hole for IC pins.

My hobby is RF electronics and I need to use squillions of vias for RF
ground connections. Some as small as 12 mil.

Any solutions (pun intended) for that problem that don't involve
buying gallons of the stuff and don't require a bank loan would be
most useful to me.
