i ran into the same issue, basically u want any type that says "safe for aquariums" on it. pet stores will carry it but i smaller more expensive tubes, u should be able to get some from a home depot/rona or ur countires equiv hardware store. also keep in mind even the ones that say "safe for aquariums" will give off toxic fumes so a 24-48 hour cure period would be highly recommended. hope this helps good luck.

i went ahead with AFM safecoat products. I used AFM hardseal, contains any off gassing from any layers underneath it. Then i used some layers of watersheild to make it really reallly water-resistant. Been using the products for about 3 months with no side-effects on my gecko!
