Rear wiper arm question

[Vova585]

Car(s) effected: XC60
Issue: rear wiper arm constantly is being pushed down below the level of rear glass during the carwash.
Observational info: issue is noted to be present on 4 of xc60 that we have in family. Saw similar issue on other xc60 around as well.
Question: anyone was able to figure out some wiper arm limiter that would prevent arm being pushed down below the level of glass abd possibly scratch the paint? I noticed that 2003-2009 4runners have special resting plastic clip for wiper arm and was thinking to do something like that. In case someone already 3d printed something or repurposed something for this issue, I would greatly appreciate suggestion.
FYI: please avoid buying Vaico brand wiper arms from fcp or anywhere else(bought mine from fcp until went and bought oem). unless you are not planning to bring your car through automated car wash. Spring is way weaker in comparison to oem and cleaning rugs(row of cloth like strips at Delta Sonic Brand car wash) lift it and on the next station(either air blower/dryer or 2nd "rug" stage the wiper is saying " i believe i can fly" and leaves the car.
