Has anyone used any corrosion blocking sprays under the dash of the truck. I took a look under mine today for the first time and saw some minor spotting and would like to keep it at bay compared to my old truck... I have fluid film, but man that stuff stinks lol. Trucks less than a year old, trying to keep it long term.
