Realized I should come back and post a wrap up for the thread I started.
I decided I did not want any hoses for the nozzles inside the cab, so hood mounted was the way to go.
I already had a bottle with integral pump like vintovka posted, it came with dual jet squirters. I tested them, their narrowest setting was a pretty wide spread. The cowl and hood brace limits how close to the windshield you can get, but with the right angle the dual squirters get one side of the windshield each - (4 streams, 2 of which cross the centre line of hood)
The bottle I have came off ebay but I see them all over Amazon. The pump in mine died after I tested it, it turns out it is a '90s civic/accord pump and knockoffs of those are also available all over amazon for cheap. The replacement has been working fine.
