I was hoping someone would have provided instruction on this one, as I need to figure out how to tighten mine down. The front arch, on the passenger side particularly, seems to be coming loose and I'd like to remedy that.
As for removal when detailing, I recommend getting a synthetic polish that wont negatively affect the plastic trim. The "Ice" line from Turtle Wax works really well. In fact I picked up the whole shabang to include the wash formula, polish compound and spray detailer; add in some microfiber and you are good to go
It actually beautifies the plastic trim parts, but it (the wax) is not recommended for use on the glass for some reason.
