I've watched many of his videos on youtube, and had seen the anti corrosion gel one before. I don't know what it is made of, but I have no doubt it will work. Its good you shared that information.

Just contributing what I did related to the corrosion. I researched how to handle this problem years ago and tried silicone grease, which is anti-corrosion as well, along with red and green scotch bright pads. I was very pleased with the results and the areas have stayed free of any new oxidation.

Silicone grease is an excellent rubber door and trunk seal protectant. A very little bit on the inside of spark plug boots make them easy to go on and off. A little bit in the side marker light sockets prevents corrosion there.

Here is a link to what I purchase:
