Copper Naphthenate

[Grant]

I cross-posted this subject up in the Bee Forum (more visitors to that area). But I'm going to re-post it down here because this is probably where it really belongs.

I've searched the archives on the subject of copper naphthenate as a wood preservative, specifically for hive bodies.

Yes, I've read the posts of those beeks who think it poisons the bees. Yes, I've read the merits of a good coat of paint. Yes, I've read all the opposing viewpoints and alternative suggestions.

All duly noted and respected. Thanks.

I would like to hear from those who actually use copper nap. How did you apply it? What did you dilute it with? How's it working for you? Satisfied, or after using it would you go with something else?

I have been using it on my pallets. I apply it with a garden sprayer, low pressure so little overspray. I just dug out some 15 year old pallets to use and the 2x4s and runners underneath were all sound, no rot at all. I have had problems with paint adhesion afterward if not thoroughly cured.

we dip all over our hives bodies in it. i gal copper naphthenate to 4 gal paint thinner. done it that way for years and had no neg effects

I have hives that are:
1. Painted
2. Copper/N
and
3. dipped in wax/gum rosin.

Bees seem to do fine in the C-N and I haven't experienced problems associated with the C-N that I am aware of.

The hives/covers and BB's don't weather as nicely as the wax/rosin dipped equipment. The C-N hives have been weathering for many years with no rot. The outside grain is much rougher then the other methods of treatment.

What would be wrong with adding some copper napthenate to the wax and gum mixture for dipping?
