Hardman Epoxy-Orange-Very High Peel Strength Epoxy is a good choice for the job.
But the little cut-up steel wool was not. For future reference if you want some extra strength mix in some glass fibre strands which you can get by picking apart some glass cloth. N.B. Do not use strands from the random mat as the binder most used does not dissolve in epoxy so there is no bond.
Neat job though!
