Dunking is a good way to hurt ring seal and seating. Moly rings are coated with molybdenum and they require a very smooth honed finish. It's called plateau honing. When you have the right hone finish, and the right rings, you need very little. I use Wd40, no oil at all. Total Seal has a special powder to use, and I know guys that use ome graphite powder instead. but use of oil on moly rings is not the best way. As I said, it means the rings may not seat for a while. They should seat virtually immediately, the light oil lets it.
