This stuff rocks. Available in spray or dip form, I use it on anything and everything from tool handles to 2.4ghz wardriving antenna. It’s available in most home improvement stores (Lowes, Home Depot). I prefer the dip for small things like keys and tools and the spray for things that are bigger.
A cool tool is anything useful that is superior to comparable items. If you think this tool is inferior suggest a better one. You are welcome to insult a tool, but comments containing insults to individual people will be deleted. Corrections of fact are always welcomed, if stated politely. Recommendations of better tools are dearly wanted and may be elevated to the front page.
