I'd try the same, it's close to perfect. If it will pinch together it may be enough to hold it and leave the rest untouched. If it fails then can try something more drastic that requires sanding and painting the lot. A modellers trick is to mix a little bicarb soda into the glue to create a filler that sets, or fill the gap with the soda then run the glue over top once pinched. It makes any filling easier to paint, using regular type paints, anything larger than a touch up may still need flexible dash filler. Either way, don't make a mess of the glue when you wipe it off surrounding dark skin, can become like a glossy seal to any future protestants or cleaners once dry. But obviously you know the basics of super glue and the mess it can make.
