Correct. Upon reflection I didn't really answer the original question.
@BernardBlack - yes linseed oil is good enough / perfectly suitable for treating cedar hives and stands. It's a pretty impressive wood if you care to read up about it. It's resistant to rot and decay and also offers a natural resistance to bugs trying to bore into it or whatever. It apparently has a certain smell to it which insects don't like & naturally contains a chemical called Thujone (Red Cedar doesn't) which causes nerve damage to any insects foolhardy enough to try and mess around with it. I expected it to be a hardwood, whereas in fact it's a softwood.... albeit it a very strong one. Life expectancy - 20'ish years.
If you don't treat it, it will naturally weather over time and turn a silvery / grey'ish colour. How long will this take? It's all to do with the amount of sunshine it's exposed to, however, it could be as little as 6 to 12 months in a sunny location. Treatment will extent it’s life, however, at 20 years do you really care? For me, treating with with linseed oil is about aesthetics and personal choice. For example I also paint some of my hives and accept that from time to time I’ll have to do it again – or maybe change for a different colour. However, I like them like that and having only a handful of hives means I can. As
