I have had several guns redone with case color and rehardened at he same time. There have been zero problem with any of them. I've heard others have less positive results. The decision to redo colors is a personal one and I don't care to debate it. If you want to do it yo your gun then do it.
The more guns I've owned the less important it seems to me to recolor gms when restored. That said I have one more Lefever project gun that I am thinking of a complete upgrade, stock bent, with both barrels redone in black and white, metal engraved and case colors. A money pit of classic proportions but a gun to leave to my middle son when I can hunt no more or pass on to the limitless bag limits of the after life.
