I haven't waxed the edge since last fall, but the Collinte 845 survived the severe winter. It was just starting to not bead very much.
I washed, applied iron x then used a speedy prep towel to decontaminate the paint. I used Collinte 915 this time and it left a great looking finish.
I didn't get pics because it is pouring here today, but at least I know the paint is protected now.
I see a DA polisher in my future, the paint looks awesome still but I can see the start of some swirls.
