best filter for filtering shellac?
I'm making spirit varnish (basically shellac with some additives).
So far, I can tell that my brew has some crud in it from the shellac as well as some suspended particles. I'm wondering what is the finest filtering medium I can use that will filter out the stuff I don't want, clarifying the finish as much as possible, while still allowing the finish to pass through. I've tried disposible coffee filters with other finishes, but it seems that the coffee filters are just to fine; the finish won't pass through.
I've recently read acounts from folks who have used panty hose, cheesecloth, re-usable gold mesh coffee filters and regular cone type paint filters. So, what's the finest filter medium I can use to filter out the most crud wheil still allowingthe finish to pass through?
It would be nice if panty hose and coffee filters included a micron rating :)
