Hi Group: Where can I buy fluids for blackening aluminum and/or brass in around 75 to
100 oz. bottles? I only find sources who all sell the same 3oz bottle from BIRCHWOOD for between $6 and $8. This is very expensive because the fluid istelf is very cheap to manufacture. Maybe chemical hazard regulations are behind just offering such small quantities. I found some good recipies for making such fluids - and I would do this - but then I do not know where to buy small quantities fo the chemicals either? Can someone help? Alex- posted
