Phil tipped me off to a product called Puzzle saver. Its basically an acrylic varnish. Non-toxic, dries clear, and FAST. Fun stuff to work with. It's like smearing watered down glue all over it.
does it dry hard? guess it must do. but say, if you sealed say a piece of paper, would it still be limp, or like as if it was laminated? it a watery liquid?>
When are you going to make some caves that are really out there for your L260? Come on, bamboo, pvc? Your poor plecos are going to think you are setting them up in a one night stand motel 6!
