OK, that is a thought. I suppose the extra ethanol wouldn't hurt since I always add some at coating time anyway.
I should have added that this batch of dropper bottles I have has ml marking on the droppers and also since it is roughly 20 drops to the ml that is why I said about 8 drops.
I also have 1ml syringes.
Anyway, then it seems like I am thinking along the right lines? At the cost of this stuff I'd rather not mess it up! (Actually, what I have was pretty cheap, but to replace it won't be.)
Thank you for the info!
