I did it once to a Meucci.
I put the butt on a lath and taped off the wood from the wrap.
I spun it up and broke the coating with rough then finer sandpaper almost to the wrap.
I then used paint remover(I think thats what it was I did 25 years ago)
It dissolved the remaining coating and I used a rag with remover as the butt spun to soak all off.
I let it dry and pressed it.
Came out great.
