Vintage Martin Grain filler

Pukulele Pete · May 23, 2011

I've been watching videos and reading about grain filling and I wondered
What the Martin factory used in the 30's for a grain filler ? Did they use one?

For anyone interested so far I have found out that they used to use a product called " PORE-O-PAC " but I'm not sure when they started using it.
