Sealant

[Summerrayne23]

Hi everyone. I am building an enclosure and am looking for a sealant. I am putting a picture across the back of the tank. I have seen that many use modge podge in the DIY rocks as a sealant. Would modge podge also work to seal the picture to back of tank? I know it would seal it but would it withstand the heat from basking light? If not, what is recommended?

Paper shouldn't have a problem holding up to the heat of a basking light. I just have my photo background held to the back with some glue dots. Mod podge might work for a more permanent assembly though if it's sticky enough.
