That silicon doesn't dry clear so you would alter the appearance. I'd think there would be some form of polyurathane that could be used but I just don't know which one it would be. That would have to be a call to the manufacturers.
Now, having said that, I do know that on an episode of "Tanked", they needed to seal some unique decor for a tank so that may be a phone call worth making.
