Just watch the tinned 2 part fillers, the lids often fit "right from

Those deep set lids are a pain, presumably designed to incorporate the
hardener, and possibly supply you with a mixing receptacle.

Ebay had a lot of out of date hardener on it last summer, beware oddly
cheap stuff.

I never seem to use all the supplied hardener, so I have plenty of
spares. Why some are the same colour as the resin beats me.
