How to make fake metal look wet?

[chimerasoup]

I'm slowly putting together a drowned deep sea diver costume, mostly made of EVA foam, upholstery foam, and cardboard.
I want to try and create the "just crawled out of the depths" wet look, but I'm hesitant to use the can of spray gloss sealant in case it simply makes the "metal" look polished and not wet.
Is there any painting or styling I can do to prevent that? Would a spray gloss even work?
Much Love,

I would think that some of the fake water products for modeling might work...

I use this product for wet look. I use it on statues and masks to gloss eyes, and lips. I even drip it and it dries like clear water dripping. It works great.
