Paraffin is the classic sealer for green wood. The wax must be heated very hot
(just at smoking) or it will not penetrate into the wood and the wax will crack off.
Emulsified wax such as Anchor seal works reasonably well and is easier to use. Be sure to coat 2X for best results.
If you are cutting squares for spindle turning, dip the ends into the hot paraffin or paint on the emulsified wax. If you are cutting rounds for bowl blanks, the entire surface should be coated by dipping (paraffin) or brushing.
The waxed turning stock should be stored in a cool storage area away from heat and dry air.
If you are cutting boards or slabs, first coat the end-grain (as soon as the logs are sawn) with emulsified wax (Anchor-seal for example). Start a stack by placing 4x4s under the first layer 18" on center and 4 feet long. Stack the first layer of lumber across the 4x4s. Place the stickers (3/4" thick by 1" wide by 4' long dry sound wood) just inside the ends of the stack and then every 18" directly above each 4x4. The stacks are best managed when they are roughly 4 feet wide, 6-12 feet long (depending on your lumber lengths) and no more than 5 feet tall. Place the best boards near the bottom of the stack and "junk" boards for the top layer. The stack should be in the shade, but with good air flow through it.
This approach is the best way to allow the wood to start drying with the minimum problems with either mold, rot (from being stacked without stickers) or drying defects from improper stacking.
If you want to air dry the wood, leave it in the stack roughly one drying season for each inch of lumber thickness.
Good luck.
