Decal Remover

Hi folks,

I’m wondering if anybody has used the decal remover from Joe’s Model Trains, and if so, what was your experience. I just purchased a used brass Western Maryland decapod that is decently painted and nicely weathered, but is poorly decaled and with incorrect road number. It sure would be nice to be able to change the decals without repainting the whole model, but other solutions I have tried, do too much damage to the underlying paint.
