Northern California or Oregon  can it be bought???


Yes You can buy it from Post Apple Scientific inc. in PA 16428 and it will  
waterproof cob however; I have heard that if the waterproof surface gets 
damaged  and water gets into the cob it will not allow water to evaporate properly. 
I  have had good luck with linseed oil. It penetrates deep into the cob and 
forms a  deep waterproof layer not just a surface cover. My playhouse at Green 
Spring has  had 60 inches of rain with no roof or water protection what so ever 
other than  the linseed oil.
