if you can't use it yourself [watch that Imron!!] or find someone else who can use it, check w/ county gov re hazardous waste disposal - don't send it to the landfill even dried unless it's latex -
if you\'re Tacoma/Pierce county or
King county there are possibilities - other areas should have ways to deal w/ it too, as WA has a fairly good rep for hazwaste handling [which is what "solvent" base paints are]
