I see why the link didn't work.. that was a link to load the pdf off a server.. try this link to the title page on their gear plus page. Mid way down the page you will see a link to a pdf file.. it says this:
"""For more technical data, see product data sheets. """
This PDF that loads up is for the gl-4 gear plus lube.
I'm not sure what you read.. but in plain english, in the first paragraph, it clearly states that it is bronze safe.
I have added red lettering and italics to the section that says this.. ( if I did it right.. ).
