I recently took a trip to northern Michigan which has lots of beautiful rocks. Of course, they look much better when wet. I brought some back and would like to find something that will make them look wet. I've seen rock art that seems to do that. I tried Home Depot's "tile lab gloss sealer" which someone here (slowmedown?) had recommended when I wanted to make my beach glass look shiny/wet. It works OK but not great on the rocks and I'd welcome any advice on any other products that anyone else here has. Thanks!
