Having a stroll through the middle of Lidl, like any good 40 year old man does, I came across some sprays.

Nothing too remarkable about that. These ones were a set of liquids intended to be aerosolled into various bits of a car engine…

Engine Starter Spray: Fair enough. I’ve never needed such a thing, but I can understand why it exists.

V-Belt Spray: Again, I’ve never needed such stuff but its existence makes sense to me.

Anti-??? Spray: It protects your leads and cables, apparently you need to do this. It has “Excellent adhesion” and “Lasting protection”. But from what?

Competitions seem to be all the rage on the Beans lately, so what do you think? What common engine based malaise is this spray protecting from?
