The hot glue hardens to about the same consistency as the base plastic. Not too hard and brittle, but not too flexible either. I think it provides some really useful strength to the repair.
I use it for lots of things. I like the fact that you don't have to wait for it to dry. I recently patched the rear bagger on my ride-on mower. I used some shadecloth to cover the tear, glued it all together with some hot glue and sprayed it with some black paint. It looks neat and its probably stronger that ever.
I also used it to repair a crack in the plastic wheel flare of my Pajero 4WD. Even without any 'welding' its still holding together after about 2 years. Surprisingly, spray paint seems to stick to it pretty well if you rough it up slightly.
