I am currently working on a Madrone live edge slab. My problem is that it has a few small spots where there's rot and the wood is punky. The rotting has created some beautiful spalting but as i said,some spots have gotten punky and I would like to know if using Clear Shellac (Zinnser Bulleye) is a good choice for stabilizing/hardening those areas. I am about to use some black colored epoxy resin to fill all of my cracks and voids and then sand and finish. Should I just dig all these areas out and fill with epoxy or is the Shellac a good way to fix these spots so I don't have to dig them out and I can keep the slabs natural look and color? TIA.. by the way I tried several times to add pictures but it keeps saying the files are too big.. sorry..
