My research was indicating that most of the UV degradation came from UVC rays which are more often reflected back by the ozone layer, however I do think that if I were to sell them I’d probably go the ABS route with an acetone bath to seal it since it’s a bit of a stronger. Thats for another discussion though.
EDIT: Looked into it a bit more, I was thinking PETG would be significantly more expensive, but with them being a similar price to ABS I think a solid route would be PETG as you mentioned and spray on a layer of UV protectant clear coat.
