I have about a dozen rifles and basically shoot two on a regular basis.  Anyway, I've applied Break Free Collector to the other rifles and only have about one year's application.  Does anybody have any longer term experience with this stuff - like 4 or 5 years?
   Also, does anybody have experience with Poly Bags or silicon coated sacks for added protection over rifles?   My rifles are stored in a safe with a safe heater in the basement.  Thanks for any advice.

I have kept some of my weapons in a silicone sock,after i have put a good liberal coating of breakfree clp on them for several years with no problems!!!
