Retrobright for endcaps?

[Boondocker]

Thinking about how to refurbish the endcaps in the '68 Tradewind. The endcap pieces will be retained in the rebuild but need refreshing as they have yellowed/aged.
It looks to me that they are ABS plastic and that a mixture of hydrogen peroxide and cleaners called Retrobright has been used on AS plastics in the past. I see a number of posts about this from 10 years ago but nothing more recent.

Is Retrobright the way to go for endcaps, how does the refresh hold up over time? Other ideas- I DO NOT HAVE INTEREST IN PAINTING THEM.

Did you ever end up retrobrite-ing your end caps?! I'd love to know if it works...

I also wonder if it wouldn't relieve some minimal yellowing on my vinyl wall coatings, which I prefer to preserve/leave.

I expect the results might be rather short-lived in either case, assuming there are results-- but maybe I am wrong! Have never retro-brited anything personally. But definitely wouldn't mind doing it every 10 years as a refresh, if that's even reasonable...
