Help and suggestions: fix cracks in abs plastic

[b1k3rdude]

I've heard of a trick involving superglue and baking powder, I think the trick is to vee the crack a bit and fill with the powder then flood with superglue, it's supposed to bulk it up and cure it almost instantly

There are proper kits (https://www.amazon.co.uk/Q-Bond-QB2-Stro...B002XF4S6C) that use this method and come with some kind of powder. Strong but a ridged, inflexible repair.

use a soldering iron on the back to "weld" it back together then the front just needs repainting to hide the remnants of the crack.

Heard of this and there are proper kits for this that come with metal staples you melt into the plastic across the crack. Both methods create a ridged, inflexible repair.
