I own my own detailing business and im always looking for fast results especially when doing dealer cars. jus curious on what every has tried and what works the best and the fastest. and im asking for the best combo for the flex 3401
I changed the backing plate of my old 3401 and noticed the inside had grease in it. Then I jus got my new 3401 and looked inside and it was completely dry. I'm confused. Is it or is it not suppose to be Greased up???
