Hey,
I have been wanting to try this for a while-- using sculpey to cover up the ugly black edging on an aquarium. I'm worried about the humidity, though. Has anyone done anything like this? What kind of waterproof sealant should I use?
Would anyone be interested in buying one? I can't explain the project too well but I will post photos of the completed work in the Misc. Completed Projects section once I finish.

Polymer clay is fine to use on the outside of an aquarium (re health of the fish, as well as appearance of the clay)... so as long as you mean the outside, that should work fine. 

Polymer clay is for all intents and purposes waterproof on its own, and needs no sealer.  If polymer clay is submerged in liquid for months though, the very surface ot it may begin to absorb a bit of water, resulting in what looks like a whitish coating (that doesn't show up much on lighter-colored clay). 
So exposure to "humidity" is fine... it's just any continuous and significant exposure you'd want to consider (and even then it wouldn't affect the strength of the clay, just the appearance of darker colors).

You can read more about polymer clay and exposure to water and humidity, bathrooms, etc., as well as sun and outdoor elements, on this page of my site if you're interested:
http://www.glassattic.com/polymer/outdoor_snowglobes_fountains.htm

One thing you might want to consider though is that "Sculpey" (actually Sculpey, SuperSculpey, Sculpey III) is the weakest of all the brands of polymer clay after baking when it's thin or projecting.  It'll tend to break off, chip, or crack if stressed. 
Your clay coverings may never be stressed, but if they will be, you might want to use a stronger brand of polymer clay instead (Premo, FimoClassic, Kato, Cernit... FimoSoft is probably medium-strength in those thin areas).

HTH,

Diane B.

Thanks so much. I may be transporting them to various craft fairs or even swapping them depending on how successful I am with them, so I thank you for the stronger clay suggestions. Once again, thank you thank you thank you!! Grin
