Haven't seen the new issue yet, but I think it's a great idea. I would think that when the first bottle gets too grungy, you would replace it with a new bottle, then make the original second bottle the new first one, and so on. I'm gonna try it.
Also, empty Fuji Film cans make great containers for this, and you may be able to get them free at a photo shop, or maybe the One Hour Photo dept. at Walgreens. Just be careful when you open them, as the cap fits really tight. I have several and label them each for lacquer thinner, denatured alcohol, Future, and also thinned mixes.
