That's impressive. I am curious how you were able to salvage the labels.
As Pixelgeek noted, the GW, and also the Foundry, labels all peel off pretty easy. The GW ones are plastic so they peel much easier, but with some care and gentle persuasion the paper labels as you can see can also be removed and put on new bottles. For me it was not merely an aesthetic choice that the new containers look more 'professional' but that they are actually easier to read with the original one on. That said, the company label was much easier to deal with than the specific paint name and number circles, these have much worse glue and even when on their original bottles tended to fall off and get lost. So as you can see there are a few instances where I was forced to create a new label or even use clear tape to secure the old ones. Overall a small price for the bigger convenience!
It was a week long job, but for the 35-40 bucks in materials, well well worth the effort!
