My main concern was if i used the paintbrush then if i'd by mistake apply too much in one place then the paint will start to run... which would be horrible as it would destroy the entire paintjob.. so i was thinking that the paint would dry faster with the more volitile alcahol.
I was also hoping that the alcahol in the windowwash would make the dropplets smaller and create a better mist.
The idea of the windowwash in the paintbrush was because some have used acrylicpaints mixed with windowwash to weather their items..
