Storing 1 Shot in Plastic Bottles

Is it acceptable to store my 1 Shot Lettering Enamels in squeeze bottles?
While it's acceptable, there are a couple of important points to remember. Normal "plastic" (PVF, PVC, etc.) squeeze bottles, as found at beauty supply centers and even through some sign supply sources, can allow for plasticizer migration, from the bottle to the paint; resulting in slower drying times, lower gloss levels and ultimately, reduced exterior durability.

Make sure the bottles you store your 1 Shot in are made of PET (Polyethylene terephthalate ); and it's advisable, when practical, to store those bottles upside-down, to help prevent skinning over of your paint. When storing 1 Shot Metallics or Pearlescents in PET bottles, drop a ball bearing into the bottle, to aid in thorough mixing when shaking your bottles.
