Ok, have large block (about 90 cm wide and 12 cm thick) covered in Metasequoia leaves and carbonized wood that due to being partially wet when I recovered it I used white glue to lock the carbon in place. My question is, now that's its totally dried out, can I put Vinac over that to help with the whole block, add more glue, remove glue (if possible?) then do Vinac, or just leave it be?
I doubt there is a perfect solution but with the knowledge here maybe there is a usable answer
Thanks, Steve
