IDEAL Electrical 30-031 Noalox Anti-Oxidant Compound, 8 oz Bottle

Works great for aluminum connections.

I like this size container - makes it easy to use.

Works great.

It's the Never-Seez for brass and aluminum. Keeps screw-in light bulbs from sticking.

This is a great product for assembling amateur radio antennas and will keep mast sections from corroding together.

I am an electrician and use this for 250 mcm service wire terminations. I have always purchased the squeeze bottles from my supply house and just removed the cap so I could stick the wire inside and get it coated up. But this is a game changer! When I saw this I was like YES!!!! It comes with a brush just like a pipe glue bottle albeit the brush is too firm and should be more of a brush than just a bent flat point. But it goes on so much easier and no more trying to squeeze the stuff up to make it useable.

Needed to prepare Aluminum WIRING for use.

This is a good product that I have used for years to cope with aluminum wiring. It is still the same dark gray gooey stuff but works well. It is a bit lower in viscosity (supposedly) than another advertised brand but I prefer this particularly for stranded wire. I recommend this product.
