Your medallion failure may not have been due to poor preparation, but by poor choice of adhesive.
Glass and steel have different coefficients of expansion as the materials react to temperature changes. ...I suspect the JB Weld did not accommodate the difference.
I once tried gluing a ridgid plastic nameplate to flat stainless steel. ...Several attempts using different adhesives failed. ...Silicone caulk/adhesive was the final attempt and was successful.
The silicone was flexible enough to absorb the expansion & contraction of the stainless, which was greater than the expansion & contraction of the plastic.
