FicTech foam is unbelievably easy to use. Just pour into a foam gun, point and spray. The bubbles do the work. I usually go over the entire car with a micro fiber mitt, once that’s done, uncouple the container from the nozzle and rinse! Drying the car is simple, get a few old towels and blot the car. No streaks or spots! If you wash the car weekly, get the 5 liter jug, it’s economical.
