Well, I use rain-x, but have seen a change, and want to reapply it. I bought a new bottle ( apparently new formula ) in the shop yesterday and want to go at it tonight...
Car is washed and dry. Do I use for instance Jeffs Prime first to completely strip the previous stuff, and then apply as the bottle says?
