I am trying to make a background that needs to be sealed. It won't be completely underwater but will have to endure water splashing dripping off of. I am looking for an aquarium/fish safe product that is cost effecient(cheap). I found this as the cheapest possibility. It says it is used in marine applications, do you all think it is safe? The stuff that is specifically for aquariums is so expensive and am looking for a cheap alternative, so if you have any other suggestions I would appreciate those too.
