iirc, Bob was using material from Scott at Palmetto. I called him about a year or so ago & he was getting out of the business. But I see his website is still up. I think thats were I stopped as I wasn't sure where to get the chemicals. I recall something about the Palmetto being a darker black than the others. Or something along that line.

I had so many other things to do I just put it off until now. Just need to make a laundry list of things to order. I think Bob had some videos too? I forget......
