I prefer the shellac paints such as Zinnser BIN. They dry much faster than either waterbased or oil based blockers.
On the downside they are slightly yellow and will probably need to be touched in with 2 coats of white emulsion.
When using household ammonia, the brushes are extremely easy to clean.
