Ok, so I understand correctly Chuck:
1 -you rub in heated sap - so your melting and applying it - OR- your using soft pitch and rubbing it in like bees wax?
2 -THEN you take charcoal ash (or just ground up charcoal?) and rub that into the already applied pitch from the above step until the pitch looses it brittleness?
thanks, just wanna get it right!
