Also, make sure you don't wind the line too tightly. Don't leave it loose and sloppy on the spool, but many guys wind it too tightly and have feeding and breaking issues with it.
mine has done that after sitting in the warm shop and just gets brittle, I bought a new spool and it was fine. I then took the other spool and left it in a bucket of water over night and it was fine.
Never tried WD-40 but seems like it would work.
