I really have no idea, to answer your question. I've actually never used glossy paper. But, I have used the Krylon matte finish stuff to spray over things done with Pearl Ex - and it kept the PE from rubbing off. Maybe try both - heat set - but keep the gun far enough away so you don't burn anything (and keep it moving) and then spray with Krylon. Then you should be good to go - I would think. I've never tried it though, so I really am no expert. Let us know if you try it and it works.
