Query: Better than chewing gum

This glue is extremely thick. Instructions say put glue on parts and leave it for 10 minutes before putting them together, but it's too late after 10 minutes. Maybe the one I got spent too long on the shelf, but that's what I was sold. Unlike other plastic cements this one doesn't melt plastic (which means it won't work well). I used (well, tried using) it on plastic aircraft models and got mediocre results. Parts fall apart with the lightest pressure. Any glue that is left on the surface of the plastic parts can be rubbed off with a finger (even long time after gluing). If it didn't work on these models that are not too hard to glue together, then I am not sure what at all it can work on.
