Good deal man one more ? On the Window Wash how many gallons of it to how many gallons of water?Water...you can use tap, spring or distilled.
Meth...you can use window washer fluid with no soap, straight Meth, or air brake conditioner (it's basically just methanol)
Ratio...30% meth is a good safe start and will keep your system from freezing in the winter. You can go up to 50% or more meth as long as you have your tunes adjusted for the timing the methanol advances. Remember it's a fuel so you need to adjust your tunes likewise.
