Message: [QUOTE="mrlewp87, post: 154210, member: 94692"]On a related issue, building antennas has become a real hobby for me. I've yet to commit to the best in metals, due to price, so corrosion is a concern. When I'm making numerous connections, and sometimes mixed metals- alum., steel and zinc coated for ex., rarely copper, what could I use directly on the parts before tightening down? Meaning nuts, small bolts and washers, plus my own cut phase ligns- thin alum. strips. I have Ox Gard (name?), and a 2nd similar ooze. Are they more for an after-coating? Before running out of it, I was using a red anti-corrosion spray meant for battery terminals. Sure, it rinses off the exteriors, but I'm interested in the metal to metal surfaces and conductive properties.  [/QUOTE]
