superglue can eat the paint and sometimes even the plastic (pretty rare though).
I would not trust superglue for anything but where it can be hidden.
It's just easier to use a gloss varnish if you really want a detailed paint job and reapply it every so often.
Anything that's handled gets recoats, even kitchen countertops and floors made of concrete or stone.
Fact of life.
Krylon Fusion is great if you just want color and leave it as is.
