Where the sealer makes the biggest difference, IMO, isn't on the log but rather on the lumber as it is dried. I know a few who seal the ends of the boards before drying, and others than seal the logs before milling. Either way you have sealer on the end grain before the lumber is dried.
I seal the ends of the logs, and with paint the grit is hard on blades... On painted dry lumber, i had to cut the ends off my boards for the same reason, hard on tools.
NOT SO with Anchorseal! You can saw right through it....no problem at all.
