Thorin,
Take some glass wool and stuff a medium sized funnel with it. Use enough
glass wool to fill the funnel up to about 3/4ths of its volume. Then press the
wool down to make a sort-of-tight fit inside the funnel. This last is to
ensure that no paint lumps can pass through the wool. Then pour your paint in
the center of the wool pad. This should hold the lumps from passing but allow
the liquid paint to flow into the container below the funnel. May take a bit
of experimentation to get the hang of it, but it should work.
