I know it's the total opposite of what this forum is about but does anyone know what i can use to keep some slabs of wood from cracking? I cut up a dozen slabs of beautiful elm to make backers for some of my deer skull mounts. Someone told me to use polyethylene glycol to keep the green slabs from cracking? Any idea if it works and where to get it? I've also heard of using mineral oils, and even bees wax???
