Jigman the thing about cedars that makes them good eterior woods is their natural oils.,which can also cause paint adesion problems. the other thing is that all woods will absorb moiture thru its end grain. by sealing the wood you will lessen this problem. the guy you mentioned on the other site, does he use water based or oil based paints. i use oil based primer and oil based paints and haven't had a problem with any paint peeling . i use AYC, maple , cherry birch, poplar and mahagony, depending on the plug. take a piece of wood weigh it soak it in water then weigh it again see what happens.
