Most was about a month old. Ok Ill try it.
Yeah, she can definitely get brighter. I usually purge 2 days, flip and purge 2 days, and then I do that one more time for a total of 3 flips and 6 days, that's my minimum. What temp are you using, stable stuff like that should be fine at 90 to 100. Once it starts stabilizing there is too much tension on the bottom surface to purge quickly, so you have to flip in order to get it clean. Even product that looks as beautiful and clean as that can be essentially butane soup if you don't flip. Butane keeps it sticky and dark, after flipping it should be brighter and more stable. Don't put her in the fridge or freezer if she is too tacky to flip. Put a thick baking sheet in the freezer and towel it off once cold. Use that to get the paper side cold so she transfers to a clean sheet easily. Work quickly so you don't get condensation, the whole idea is to avoid moisture which could add an extra day to your purge.
