Thanks, Ken! I thought about trying to hide it with paint, but I was afraid I'd just make it worse. If I didn't have any other decals I would have done that. As it is I used some adhesive tape, burnished it onto the decal, and it lifted right off. The only paint under the decal is the light gray wash used to represent the mortar joints. I got the new one on. I used the MicroSet underneath of it, and MicroSol on top. It's drying right now. I'll give it 24 hours to dry and then seal down the edges.
