Hey, Philip, Jeff is spot on telling you it's the ratio that counts, not the end amount. For small amounts I also use those oral syringes for kids (we have a store here called Kroger's that gives them to me for free and they're above average because they have no rubber in the stopper and that makes them last longer) and I also like to use a pipette with a bit of masking tape wrapped around it for a fill line. Just draw up 5 of one and two of the other and I'd be set.

I've done a lot of experimenting with oral syringes for smoke fluid and one thing I've found is that some products can have a reaction to the material used in the stopper/plunger. Stock Taigen smoke fluid will mess up some rubber in a hurry and the whole thing will lock up tight and be useless. I imagine you're using acrylic, a waterbased paint, so you shouldn't have all the trouble I've had with smoke fluid and enamel paint. If it wasn't such a long swim I could mail you some of the Kroger jobs, the best I've found. Maybe one of these days I'll have to send you something, so if I do remind me to send a couple. I get them free. I wonder if a syringe video would help anyone?
