NO!!!!!!!!!!!!! Bubble can leave imprints and tissue can stick to the gloss. Storing glossy figures for periods of time can be tricky. If the "gloss" varnish - what ever it is - if it is thick you can pretty much bet that there will be problems.
I would use paper - like gift wrap or a slicker type - nothing with fuzzy or "teeth". Also, a foam type material is good - the density that many of the K&C sets come with, Trophy, etc. Imperials foam was too pourous and would sometimes stick to the gloss.
The alchemy of storing figures can be tricky.
