Are all hardeners for these types of 2 part fillers the same. I have some metal filler but not enough hardener came for it all. Could I use the hardener that comes with 2 part wood filler with the metal filler?! Are all these types of hardeners the same? Thanks for any information.

Thanks wood filler hardener would likely not cut it. Different consistently?

Check the label on the original tube.
Likely - but not nailed-on certainty - that it will be the usual BPO (benzoyl peroxide).
But for complete peace of mind I'd suggest getting more of the same that came with your filler.

FWIW as an example Isopon's website says in respect of their own range 'Can be used with all the U-POL and ISOPON polyester fillers. Unique sachet packaging and tube for U-POL dispenser.'

Usual issues are either not adding enough which may cause failure to properly harden - or adding too much which may then bleed through any paint you put over it.
Using too much is the usual reason for running out of hardener while you still have filler left.
