Plastic (and other stuff) repair

[CROSSBOLT]

Others say baking SODA (NOT POWDER) works better than cigarette ash...

Yes CROSSBOLT,
made the same experience with fine wood shavings (dust), file shavings from metals like alu, brass, tiny cutted glass fibers and of course fine shavings from plastic covers, depending on what item is to be repaired.

Gets pretty hot for a moment, wear glasses and keep your mouth and nose away from this toxic fumes.

Cheaper than JB Weld, but better?
Good to know in pinch, though.

Now, I would not go that far! JB Weld is pretty hard stuff to beat. Even that two-part epoxy in the paired syringes work nicely if done carefully

It's the plastic panel and simple versitility of this scheme that is impressive. Never seen it before although many others already knew!
