It always DOES (hold up that is)!!
I throw a coat on there every time I wash my baby, between the salt soup in winter, and the effing never-ending abrasive pollen/'tree droppings' in the spring/summer (made even worse by the intermittent, sprinkle level rain etching it into the paint
), it is never too much as far as protection goes.
I have to get some of that Stoner, or Mother's or whomever's black trim restorer stuff, since i am not as skilled as everyone else in keeping the 845 off of those sections, especially around the front lower grille and back lower valance areas.
