Not worth the headache. If anything I think it would weaken your bedding because steel wool is not a rigid material. Thus it would just create a bunch of soft flexible channels in the bedding.
On another note, use the Devon steel "Puddy" for bedding, not the Epoxy. The Epoxy is weaker and a lot more runny. The Puddy has a creamy peanut butter like consistency when mixed properly and is much easier to work with.
Now for scope ring bedding, I do like the Epoxy better because it is much easier to mix small amounts and you only have to apply a somewhat thin layer on the rings
