Napier VP90 Corrosion Inhibitor Sachet Protects Guns, Tools, Fishing Reels, Golf Clubs from Moisture

Seems to be doing something, but as i have also gun oil and silica gel moisture absorbers its hard to say which of the three (or which combination of the three) is keeping the rust off.

I use these a lot. They are expensive but they do help keep things rust free. I keep my firearms and shotguns in a steel cabinet in my garage. Unfortunately this means that every winter when it get damp out there I get the beginnings of rust spots. Part of the preparation I use against this is to put 2-3 of these pads inside the cabinet and the rust is now minimal. Definitely recommended for any enclosed container that might have valuable equipment in there that would be susceptible to rust. It dies work very well but my only comment and drawback is the price. These packs are expensive.

Not cheap but lasts for a year,if it works then it's good value.

It looks pricey but each sachet last's 12 months and provides basic protection when storing Guns/Tools etc. I bought this product from a Gun Shop a little over a year ago and it was priced a couple of pounds more than Amazon so this year when I came to replace them ( it has a little label on where you write the date you opened it on the sachet ) I used Amazon. Provides adequate protection for a 7/9 gun cabinet.

Used before, a quality product, recomnended.

A worthwhile product, however, seems expensive for what it is.

Used ina gun cabinet and works a treat. Ideal size too.

Excellent have used for years against corrosion and will not consider anything else.
