Approximately how many terminals can be coated using a single can?

I believe Toni made a mistake as she must live in Bolivia because in North American it's a known fact by most everyone with a Harvard PHD in Osmosis that with the gravitational pull of Mars on our solar system you'll get 478 uses on average size terminals (4cm wide). I'm sure she didn't do it intentionally and probably went to a public college, poor thing.... easy mistake to. make! Good Luck :)

If i use this spray, do i still need battery anti corrosion washers?

I still use the washers on my car battery for added protection as they're quite inexpensive. I cut through one side with scissors and push them around the posts under the terminals. Saves me from disconnecting the terminals and the washers stay in place for years. On my golf cart, I just use the spray after washing down the batteries once a year. The spray seems to need re coating about once a year. I don't use the washers on the golf cart. So far, on the golf cart the terminals have remained corrosion free.

Is this comparable to dielectric grease, and can that be used instead of this?

Dielectric grease is non conductive. Petroleum Jelly is conductive. I want to protect a trailer 7 blade round connectors and will op for PJ.

Can I spray this on top of a little bit of corrosion? I am not able to remove all of it. Thanks.

Can you? Sure. Should you? NO. To be done right the terminal should be removed and thoroughly cleaned of all cossosion, then, apply the protective spray. Spraying it over corrosion wont stop it. If you cant get the terminal off, spray or pour vinegar and water on it to dissolve. Let it dry completely, then spray the terminals. Be safe
