Hi all, Has anyone tried Rust Cure Formula 3000 sold by Canadian Tire(in Canada) on antennas to prevent corrosion on vertical antennas ?

What type of base metal?

It appears to be a light oil. Reviews mention that it drips for a while. My concern on using it with an antenna would be if it causes a problem at the insulators.

Here is what I found on it;

Krown T-40 met all the established property limits."

BOILED linseed oil, put on thin coat in warm weather and sun will bake dry it slowly to form a thin plastic polymer type coating. Boiled linseed oil is a commonly used rust/corrosion preventive on metals such as rust proofing vehicle undercarriages and coating the inside of aluminum tubing used in light aircraft frame construction plus a 100+ other practical uses. Do NOT use RAW linseed oil.

For 10 years I lived ion a coastal community just a couple of blocks from the ocean.  Rust and corrosion was a huge problem.  Before putting a tribander and 40 meter monoband yagi up on my tower I sprayed each of them with about 10 coats of Krylon clear.  10 years later when I moved and took down the antennas there was no rust or corrosion.
