Finally got around to refurbishing my 2016 Territory wiper arms, as I had to remove them anyway for a wiper motor problem. (Full description of that in SZ Territory forum "sticky").
Would have preferred Wattyl Killrust paint, but for weekend urgency and convenience I chose White Knight Epoxy Enamel and the correct Etch Primer as a reasonable alternative. I am expecting it to last at least as long as the original coating. Also would have preferred satin finish, but could only get flat black - looks OK.
Looks good and I am happy with the job.
