Repair plastic shield? JB Plastic weld?

I would contact JB for recommendations. I think they advised me to use Plastic Bonder (not Weld) for a particular project.
On a side note, I can't count the times that I have spent more on dreaming up repairs for things than if I just bought a replacement. The latest is replaving cracked circular glass on a compression tester gage. The square of glass is cheap but tools to make the straight and circular glass cuts were more than buying a used tester just for the glass.
 
First, there are multiple varieties of "plastic" epoxy. Get one specifically listing your type of plastic (likely HDPE). I've had success drilling a couple of holes on either side of the crack and threading & twisting a piece of copper wire to hold the crack closed. I epoxied the wire down to the plastic too, so it wouldn't catch stuff. (Guess this is just a variation on the metal strap/pop rivet idea.) Second, make sure the plastic is REALLY clean, and rough it up before epoxying.

If you need plastic filler rod, I use black outdoor UV rated zip ties. Think they are HDPE, tough little guys.

Actually most are just PVC
Use the wrong plastic and you will ned up with a mess that is near impossible to correct other than a patch plate & rivets.
Lots of suppliers of plastic welding rods now days .
And apart from the JD green, most are a reasonable price.
Some where on the shield will be the recycle mark
Simply match the numbers between the guard & the filler material.
 
Looks like this edger shield is HDPE, a couple other projects have got in the way though. I have yet to tackle this one.

I just ordered a couple gator blades for the other edger to see if that helps my decision of whether to invest in this one.
