That's an essential preparatory step, IMO, and proprietary 2-part
'wood hardener' products are available for the purpose. Any
decorators' merchant will have some.

Fibreglass resin is cheaper, and essentially the same thing

It's a lot thicker than the stuff I tried, so would it actually soak into
the wood?


IME, yes. It soaks into porous wood, partly because it cures more slowly
than the resin used in body filler (overnight IIRC)

That depends on how much catalysts you add.


Put enough in, it sets in a minute or two and gets hot enough to catch fire
