Syringes are your friends!!! I use them to mix up my ratio of 5-1-10, 5 parts red copper, 1 part catalyst and 10 parts acetone. For 200 45acp boolits, I use 10cc's of "mix" per coat, 3 coats. Therefore I need 30 cc's of mix, so I'll do a 20-2-10 which gives me 32 cc's of mix. Kept in an airtight bottle it will last awhile. I usually just keep adding to the bottle, so I never really throw any of it away. For 9mm, I use about 5 cc's of mix per coat. Hope that helps.
