i use coffee stir straws to melt into cracks the red ones are thicker and work real wellYou can do a nice job of plastic welding that cover using an electric soldering iron Idve done a couple if them now
drive the hot point into and along the crack as you drag the iron along it will produce two wind rowes of multon plastic , use the iron to push these back into the trench and smooth over makes a good fix
If you can find a same type of plastic to use as a filler rod you can maybe do a better stronger well ;O)
