i knew when i purchased my truck one thing that i had to address was the window spotting from the ventshades from the PO.

cost me 9.95$ for a 20oz bottle


applied with sponge/microfibre applicators 1$ each
(i bought several as i didnt have any) they are reusable.

first i applied to the "pad" then massaged into the glass with a little pressure in a overlapping circular motion. then wiped residue off with water and water soaked towel. then used an amonia free window cleaner.

took all of about 15minutes for the drivers side. going to do pass side tonight.
