I have about 100 gallons of anchorseal. It seals wood while drying so ot doesn't split. Used on log ends, slab ends, lumber ends and round cut aka cookies on surface.
This stuff works great and is the standard in the business.
80 firm per 5 gallons. Cheaper by at least 25 than anywhere you can get it before shipping and tax.
This is direct from manufacturer before putting anchorseal brand on it.
