Someone voted for it because it was an option.. there is no way people are putting antifreeze in there.
I don't even think there is a benefit to using the sprayer in the winter.. if there is.. it's minimal at best. Hot summer days is when you need it.

You could put "urine" up there.. and some people would vote for it..

 

So, am i the only one that uses strait vodka out of the freezer?

 

Personnaly I use PIMP JUICE!!! Not many people have as much as me so they use thiers sparingly. I have juice to spare..... LOL

 

I've fitted one to my coupe and found that is best to drink the alcohol and use thewater to wet the garden down.
but seriously anything with alcohol in it will cool faster then water due to evaporation and vaporisation.
