   Cedar should be primed with an oil-based primer to reduce the bleed thru of the tannins in cedar.  I've use linseed oil primer with good success.

   This is just back prime to prevent warp from too much swelling & shrinking in the sun. Will latex (ease of clean up & less of smell) prevent excessive shrink & swell?

   Latex will allow moisture to pass through.Most of the factory pre-primed material I get is with Cabot's.the backpriming is not for the purpaoses you mention tho it make help somewhat. The main reason for backpriming is so that when moisture gets into the wall surface and behind the claps, it will not be pushed out thru to the surface where it will then force the surface paint off the boards.

   Any other explanation for the horrible condition of the siding on the south face of the building, other faces OK?

   Did you paint it?  I would guess that maybe the original paint job didn't include primer, or the wood sat too long before primer (even a few days between sanding and priming can be too many in sunshine, IIRC).zak

   I just put up some clear red western quartersawn lap siding. It looks great and I know it will keep looking great for a long time. I primed the face and back side with KILZ outdoor oil based primer. The wood soaked it up well and it will keep the siding looking great for a long time.

   No, but it depends on how cold it is. LOL!!!

   In this case probably two coats to give it a good seal of protection then I would paint it the color wanted
