cedar fence logs split- what do you fill the gap with?
 

My cedar logs have split as they dried. Some splits are two inches
deep and .5 inch wide and extend for 7 ft. What is an economical way
to seal them. I could fill with sand/sawdust and than seal over with
something? They split on the side that faces the sun. I plan on
rotating them so the good side faces out , hoping the good side does
not also split when exposed to direct sun.
