I have always like the "lifted" look of a decal on one (or two even) coats of finish. You could try and burnish the ends down pretty good...I would do this on a finished blank (not matte)...or a blank with epoxy finish thats set up for a few days.
Personally I just take it for what it is and go with...either that of just leave off the sticker. I have been making my own water slide decals with some success.
