Super glue as wood hardener

[ArcadeJason]

The problem with this method on wood is that it would be harder to sand than the wood surrounding it and getting that to flatten out would be extremely difficult .

This also isn't the best solution for repairing plastic as it becomes more brittle over time. Plastic welding is really the best method for plastics.

Depending on the type of plastic adding more of the same plastic is plastic welding.

I agree in part with using this method on wood although there are ways to sand the bogged portion without wearing down the wood surrounding it, it's not a difficult problem to sort tbh
I've had no issues with the repaired area becoming brittle on plastic items, especially areas that have been painted and clear coated and i'm talking a time span of over 10 years. In fact, i've had more issues with specific plastic "wonder" putty's falling out, cracking etc in FAR less time spans!!
