Scotty,
2 Questions about Battery Terminals. I've long wondered about the right way to use the Battery Terminal Protestant spray that can be purchased at auto parts stores.
1) After cleaning the terminals of course, does the protestant then get sprayed over the bolt tightened terminal and post AFTER they are secured and tightened down on the battery, or does the spray get put on before the bolt tightened terminal and post get connected (basically in-between the metals that connect the battery to the vehicle's electronics)?
2) Is there a better (more effective) protestant to use than those spray on type aerosols?
Thanks,

Never knew battery terminal sprays were religious.. And please don’t go about ‘spraying’ protestants!
attach the cables, spray the sealer. Aren't there instructions on the can?
Clean, tighten and then spray. Most are not snake oil. Some people have varying degrees of success. I wouldn't sell it cause tbh most cars don't need it. But if your car is prone to battery corrosion then it does help quite a bit. From experience the felt pads are practically useless though. The spray has a basic anti-corrosion chemical that coats the terminals. But of course if overtightened and wiggling terminals are susceptible and are more prone to failure so it wouldn't matter how much spray you use if you tighten the terminals wrong.
I use wheel bearing grease.
Never had any issues and would never use any such "snake oil". But if you want to used, go right ahead. There's probably direction on how to use it on the can.
Yes, the problem and the reason I'm asking the question is the instructions on the can don't aren't clear if it just gets sprayed over the top of everything after it's secured and tightened, or sprayed in-between the two metal surfaces connecting the current.
Save yourself some money and use petroleum jelly instead.
