Not the most durable clear but often works when others won't is Krylon Cristal Clear, an acrylic spray.
Whatever you use try testing first (on a trash fork, maybe) and make the first pass (and maybe the next 1 or 2) VERY light "misting" coats with enough time between for at least some dry time (but CC is very quick to dry). What the painters call "flash off", it's lost some solvent but not fully dry.
As the coats build there is LESS chance for bleeding and running, but that's why you test.
To be 100% sure
