It dries clear yes but I'm not sure that it works to make objects shiny on a card Modge Podge or similar products would be a better choice for the second part of the question. This is good glue for cardmaking - I use it for a variety of situations including: glueing card, buttons/embellishments, paper, ribbon. Dries quickly and minimum mess. Narrow nozzle reduces the possibility of too much glue coming out. Hope this helps ! Happy crafting !!!
