I have some pine boards that have sappy veins in it and they are leaking
sap. Is there any way to clean up the sap that is leaking all over the
board (stored standing up)? How do I seal up these gashes after cleaning?
Thanks

Mineral spirits and a rag will remove the tar and not harm the wood.
Shellac is the chosen one for sealing this kind of leakage but I
wouldn't expect it to hold up against a lot of sappy wood over years
of time. Several coats of shellac might do it. I might cut out
sappy sections or use the boards as a "secondary wood" where leakage
is not a big deal (garage/closet shelving, birdhouses, construction,
etc) . Expect your cutting tools will need a good cleaning after
cutting through sap pockets, for that, kerosene. Or, save all the
extra work, consider buying clear boards.
