O2 sensor break-in required?

[FlyNNN]

I"ll have to contact Permatex and get some clarification on this thread sealant.

I contacted Permatex and received the OK for this product on the O2 sensor. This is what I used; http://www.permatex.com/products/Au..._Permatex_High_Temperature_Thread_Sealant.htm

Knowing what I know now, I would chose not to use it in the future for this application and use the product branded as "anti-seize"; http://www.permatex.com/products/Au...ts/Permatex_Copper_Anti-Seize_Lubricant_b.htm

Thanks ALL for your input.
