Yes! Thank you! For me: definitely to look into and consider! These were very popular in Poland in the 80ies and 90ies - some of the locally produced cars did not have heated windows in their cheaper versions.
I have been looking for these recently, but found none. This may be an option. Not that I need the defroster in a Pagoda, but the option was there and the wiring is there, so it might be worth looking at if it is not too visible.
