"Does anyone have much experience with the 'battery terminal protector' spray?
(CRC, Gunk, Lynx, etc)"
Yes, I've used CRC and Gunk on my RE and auto batteries for years. It works very well. Only one drawback...It attracts dirt and sand quite well too.
Before I found terminal protector spray, I used axle grease. That works but is a bit too thick to get in the small cracks between the posts and terminals.
Anything to keep the air off the connection will work.
Thanks Phil,
I tried Vaseline a few decades ago, but it didn't seem to help, or my junk cars/terminals/wires/batteries were past trying to save.
Plenty of conflicting opinions about the petroleum jelly or axle grease coating... coat then assemble... assemble then coat... 1 is better than the other... the other is better than 1... if you know what I mean. LOL
The red and green felt washers work on my batteries, for sure.
Notoriously incorrect popular site says they keep the dirt from causing a terminal to terminal short due to gook on the battery case, which may be a side effect but its not the main effect.
I have used them for many years, and am confident in saying they actually stop the corrosion from happening in the first place, even where the felt washers are not touching (at the top of the terminals, bolt threads, and the power wires).
Wondering if the Red & Green felt washers would help on the bus bars, or why they would not help.
I try to keep the distribution parts away from the battery fumes.
