It's going to be for my daughter who just started high school, not going to a museum or anything, just want it to look clean.

I learned this trick from an old sign painter: leave the water transfer ON the card, do not cut out the edges yet (if you even need to as some are precut)
now LIGHTLY, and I mean LIGHTLY spray a super mist coat of POLYURETHANE clearcoat (spraycan clearcoats NOT recommended) on the surface of the decal on the card, let dry for a half hour, now another super light coat, and let dry again for another 30 minutes, repeat about four times.
now cut out the decal and stick it in the glass of water and apply to the surface
and let dry for at least 24 hours,..when you paint over that decal, it already has a protective clearcoat on it!
slick trick especially if you get some super old NOS decals that are cellulose based (those melt INSTANTLY if you apply a wet coat over them)
